Dear NYhosters,
We've patched all cPanel servers per emergency notices: https://support.cpanel.net/hc/en-us/sections/360007088193-Security
We also updated Linux Kernels and default PHP 8.3 (ea-php83 and alt-php83). As a result, websites with outdated PHP scripts installed years ago, will produce various Apache errors (500, service unavailable etc.)
To resolve such errors, please follow these steps:
1. Check disk space usage. You must have sufficient disk quotas in order to run full cPanel backup via control panel. For example, if website is over 5000 MB, you need to assign at least 15000 MB, so 10000 will be free.
2. If you have enough disk space, please generate cPanel backup via cPanel > General full cPanel backup. You may also backup MySQL data bases (same cPanel Backup page).
3. Download cPanel backup and MySQL DBs to your PC.
4. Once you download backups to local computer, you may work with errors. Please check cPanel > Errors for some clues, check configuration files php.ini in root folder, inside public_html folder etc. You should also check .htaccess file, it may contain invalid directives, outdated values added many years ago and no longer supported.
5. Some websites, built on PHP, for example, WordPress, may produce 500 internal error. You need work around PHP version, downgrade one by one, find working version of old PHP via cPanel > MultiPHP. For example, your website is running on "alt-php74". Downgrade to ea-php74, WAIT FOR 5 MINUTES, then check website. If website loads normally, YOU MUST UPGRADE WORDPRESS, install new theme, remove old themes, update all plugins or remove unused. Please don't forget to secure WordPress with Wordfence Security Plugin then activate 2FA for all admins.
6. Once you complete upgrade, please revert back PHP via cPanel > MultiPHP. Current stable PHP: 8.3 (ea or alt).
Once again, new cPanel no longer allows to run outdated scripts due to security modules. If your PHP script installed years ago, it will fail within new environment.
We do support all PHP versions for your convenience (even alt-56). Please use ALT (secured) versions. Old "EA" versions will be removed for good to prevent abuse.
THANK YOU!
