Each user on the server has a tmp directory. Due to write permission issues or other errors in this directory, you may encounter an error like the following when trying
to log into phpmyadmin.

>Access Denied

Unable to establish a PHP session.

If you believe that this is in error or inadvertent, contact your system administrator and ask them to review your server settings.

cpaneld/11.46.0.19

  Server at

To resolve this error, the following steps related to the user’s tmp directory will be sufficient.

1- Log into the server via SSH.

2- Check the ownership of the /home/$user/tmp directory. If such a directory

   does not exist,


mkdir tmp

chown username:username /home/$user/tmp

create the directory with these commands and finally grant permissions with the following command.

chmod 755 /home/$user/tmp

When uploading files via FTP with the FileZilla program, it connects to the server using multiple ports simultaneously. The security software on the server detects
these connections as an attack and blocks your IP address.

For this, you need to set FileZilla’s transfer mode to Active.

• We open the FileZilla program and go to the Settings section from “Edit”.

  

• When we enter the Settings
  section, from the window that appears, we click on the “FTP” heading on the left side. The transfer mode will come pre-selected as “Passive (recommended)”.

  

• We check the “Active” option and click the “OK” button.

  

• Set the Concurrent transfers, Concurrent downloads, and
  Concurrent uploads values in the “Transfer” section on the left side to 1.
  

The settings are complete. You can close your FTP program and try reconnecting.

You can also try an FTP program called WinSCP. This program uploads files one by one and
there is no blocking issue.

We love the internet. We want to contribute to its development. In this regard, Netinternet sponsors countless websites and social responsibility projects every year. If you think your site meets the

Sponsorship Within the Scope of Social Responsibility

Sponsorship can be provided for meeting the internet infrastructure needs of projects such as education, environment,
culture and arts, and aid and solidarity associations that do not pursue commercial purposes.

Infrastructure Sponsorship

To support original entrepreneurial ideas, Netinternet sponsors the internet infrastructure and all data center needs for projects
with content on internet and information technologies that have established their own brand.

General Rules for Sponsorship

• Netinternet sponsors internet projects with a daily unique visitor count of 5,000 or more. (Excluding associations and
  institutions sponsored within the scope of social responsibility.) Sponsorship is limited to infrastructure support only; the content, software, design, and similar aspects of the website are outside the scope of sponsorship support.

• For internet
  projects other than social responsibility sponsorships, with the start of sponsorship, the sponsorship must be announced on at least 2 social media accounts of the sponsored website.

• The website using the infrastructure provided by Netinternet within
  the scope of sponsorship must allocate a banner area for Netinternet in a suitable location on the main page. In addition, a link to Netinternet must be provided in the footer section of the web page.

• The infrastructure provided by Netinternet within
  the scope of sponsorship cannot be transferred to another person, site, or institution. The provided infrastructure cannot be used for any purpose outside of the sponsored project.

• Netinternet covers all or part of the costs it incurs for infrastructure
  within the scope of sponsorship. The planning and decision regarding this is made jointly with the project owner to be sponsored.

• The sponsored internet project can benefit from all standard support services.

If your site meets the specified
conditions, reach us via the support desk.

You can preview your site without redirecting its nameservers by using the hosts file.

The steps to follow are listed below;

1- We run Notepad as
administrator

2- We find and open
the hosts file from the Open tab. File directory: C:\Windows\System32\Drivers\etc

3- We add the IP address of the site at the bottom of the file and write the site name to the right of it.

4- We save the file.

5- Close and reopen the browser you are using, or press Ctrl+F5 several times. This way, you will have previewed
the site.

Finding the site IP address from cPanel

To write in the hosts file, you can expand the Statistics section on the left side of cPanel and find out your site’s IP address.

Finding the site IP address from Plesk panel

The IP address on which your
site runs is located on the Plesk panel homepage.

For WordPress’s permalink feature to work, request parameters need to be sent to the script. On Apache servers, this can be done via .htaccess files using
mod_rewrite.

When running WordPress on IIS, we need to do the same operation with web.config files. Otherwise, the permalink feature will not work.

If you upload the following code snippet to the root directory as web.config, the permalink feature will
become active. If you already have a web.config file, you only need to edit the relevant sections.

<?xml version=“1.0” encoding=“UTF-8”?>

<configuration>

<system.webServer>

<rewrite>

<rules>

<rule name=“WordPress

  Rule” stopProcessing=“true”>

<match url=“.*” />

<conditions>

<add input=“{REQUEST_FILENAME}” matchType=“IsFile” negate=“true” />

<add input=“{REQUEST_FILENAME}” matchType=“IsDirectory” negate=“true” />

</conditions>

<action

  type=“Rewrite” url=“index.php?page_id={R:0}” />

</rule>

</rules>

</rewrite>

</system.webServer>

</configuration>

To create a CSR code via IIS, you can use the methods published by RapidSSL. If you are making an incorrect operation, you will likely receive the following error.

There are several methods to check the status of your site without redirecting the nameservers. One of them is to disable the mod_userdir feature in cPanel. Root access is required to do
this. Log into the WHM panel and search for mod_userdir in the left menu. On the page that appears, if Enable mod_userdir Protection is checked, uncheck it and restart Apache.

As is known, there are dozens of companies and organizations around the world that monitor the mail traffic of IP addresses and apply blacklisting based on spam sent or harmful content on
sites.

The main ones are:

1. Barracuda – b.barracudacentral.org

2. SpamHaus – pbl.spamhaus.org, sbl.spamhaus.org

3. Spam Cannibal – bl.spamcannibal.org

4. UceProtect – dnsbl-1.uceprotect.net, dnsbl-2.uceprotect.net,
   dnsbl-3.uceprotect.net

IP addresses can be listed as /30 single IPs, or as subnets in sequence such as /29, /28, /27. If a subnet such as 192.168.0.0/27 is blacklisted, no emails can be sent from any of the IP addresses within that subnet. When IP
addresses are listed by any organization, a request must be made from the Removal Request section on that organization’s website to get them removed. Before making this request, the server must be checked, the account(s) that caused the listing must be identified,
and the problem must be resolved. Even if an IP removal request is submitted while the problem continues, IP addresses will not be removed from the list. After the problem is resolved, the IP addresses are typically removed within an average of 7-30 days. This period
varies for each blacklist organization.

When your IP address is blacklisted for any reason, you can no longer send emails from that IP address on your server. All sent emails will be returned to you as error messages containing information like the
following.

<code class=“php”>ornek@windowslive.com</code>


<code class=“php”>SMTP error from remote mail server after MAIL FROM:<bilgi@domain.com

host mx1.hotmail.com [65.55.37.120]: 550 SC-001 (COL004-MC4F11) Unfortunately,

  messages from 192.168.1.1 weren’t sent. Please contact your Internet service provider since part of their network is on our block list. You can also refer your provider tohttp://mail.live.com/mail/troubleshooting.aspx#errors.

In the
example above, we can clearly see that Hotmail is blocking an IP address and blocking emails sent from that IP. In addition to the blacklist-checking organizations listed above, major global companies such as Hotmail, Gmail, and Yahoo have their own internal security
systems. This means that even if your IP address has not been blacklisted by any company, these global giants may block your IP addresses in their own security systems and prevent mail delivery to their servers.

This problem is most commonly experienced on
shared hosting servers. Due to spam emails sent by a single account, IP blocks can be listed and all sites operating on the same IP block are affected. To avoid such situations, mail traffic on servers should always be monitored. Most modern programming languages can
send mail without needing any email server. For this reason, sending mail with these programming languages should be disabled against malicious use. For example, for the PHP language, mail functions can be disabled via the php.ini file. Instead, users should be
directed to send mail via the mail server on the server using SMTP authentication. This way, you can set policies for your outgoing mail and prevent spam mail outgoing.

In conclusion, the only reason for IP addresses on servers to be blacklisted is the
activities of users on those servers. To avoid this problem, necessary security measures must be taken on the servers and user operations must be continuously monitored.

Protection reports is the section where you can get detailed reports about the emails sent to and from you. There are 3 different options in this section. We will inform you about each of these sections
in order.

On-Demand Receipt Report

In this section, starting from a specific date up to your current date, you can get a report of all mail activities and have it sent in PDF or HTML format to any email address you want. The “Include Extra Spam
Table” option allows the requested report to be sent with a detailed spam table.

Periodic Receipt Report

With the periodic report feature, you can activate the reporting service on a daily or weekly basis and have reports sent to you by email during
these periods. In the periodic report settings as well, you can request an extra spam table or configure whether reports are sent with or without quarantined emails.

Periodic User Report

You can make changes in this section to the reporting settings you
prepared in the Periodic Receipt Report section. You can change the reporting parameters of a previously created periodic receipt report or add new recipients for the reports to be sent.
