Modified cPanel addons are not allowed message
Sorry modified cPanel addons are not allowed, contact your server admin for more info.
To resolve this issue:
1. Login to the WHM.
2. Click on ‘Tweak Settings’
3. Remove the ticks from the below options:
- Prevent installation of addon scripts not provided by cPanel
- Prevent installation of cPanel addon scripts that have be altered (Turning this off may be useful when testing custom addons.)
This should fix the problem.
POP3 is not authorizing to login in cPanel server
The problem is xinted had two services popa3d and popa3ds, which were interfering with cpanel secure ports as well cpanel’s pop3 service.

Restarted xinetd service

Incorrect diskspace and information in cPanel
cPanel keeps disk space usage for your entire account, email accounts, databases, and other features. These are cached for faster interactions. They will refresh once every day.
If you purge many emails from trash and can see that the folders are empty, then the emails are really gone and not using disk space. Your cPanel may still show few MB being used, but this will be updated within 4 hours.
If you import a database and can see all of the tables and data, then the data is saved and is using disk space. cPanel may still show 0 MB, but this will be updated within 4 hours.
From WHM, if we increase the total disk space for an account, and WHM shows the increase, then the account can use the new disk space immediately. Inside cPanel it may still show the old disk space limit, but this will update automatically within 4 hours.
Proxy access for cPanel/WHM/webmail.
With Linux Shared Hosting accounts, you have access to a control panel that contains the admin functions of your account. Generally you would access this using the following syntax:
http://yourdomain.com/cpanel
http://yourdomain.com:2082
This URL causes a problems for some owners, as it attempts to connect to port 2082. This is an uncommon port and may be blocked by corporate and public firewalls, thus preventing access.
If you are unable to access your cPanel using the above URL, you can access it using the following syntax:
http://cpanel.yourdomain.com
This syntax does not connect using an uncommon port, and will allow you access. The same rules apply for Webmail and WHM.
http://whm.yourdomain.com
http://webmail.yourdomain.com
Note: You will need to create A records for each subdomain above if not created by default during account creation process.
