Do you having problem to update your WordPress or plugins or install new plugins because it ask your FTP credential? I share with you the solutions if you are server owner that using WHM/cPanel in your server.

This typically occurs when scripts are being executed with the permissions of the apache user, “nobody”, instead of the owner of the scripts ( the cPanel user ).

This are solutions for your problems

1. Log in you WHM
2. Go to EasyApache 4
3. Select “Customize” under “Currently Installed Packages”.
4. Select “Apache modules” on the left side menu.
5. Search and tick mod_suexec or mod_ruid2 (you can only choose one)
6. Click Review and Provision

Your problem should be solved after that. Hope this help you
