Sentora panel not loading after reboot

[mamiemoore]

Hello,
I've been using Sentora without any issues, but I've recently encountered a problem I can't seem to fix. After rebooting my server, the Sentora control panel stopped loading. When I try to access the panel URL, I receive a "500 Internal Server Error." The hosted websites are functioning normally, but I can't access the panel to manage accounts or domains.

It appears that Sentora might still be relying on outdated MySQL functions that my current PHP version doesn't support. Has anyone else experienced this? Is there a known solution, or will I need to downgrade PHP for compatibility with Sentora?


Environment:

OS: CentOS 7 (fully updated)

Sentora version: 1.0.3

Apache 2.4, PHP 7.4, MySQL 5.7

Apache 2.4, PHP 7.4, MySQL 5.7

FYI: current Sentora release version is 2.0.2. More info on the packages installed/updated in this version: https://docs.sentora.org/?node=57

If your other sites load and the panel login doesn't work, something changed in your configs somewhere.
Check your logs and review the panel's /etc/sentora/configs/apache/httpd-vhosts.conf file entries.

Thanks for your answer. I got it.

The 500 error is due to Sentora 1.0.3 not being fully compatible with PHP 7.4 (it relies on deprecated MySQL/PHP functions). Your sites work, but the panel breaks.
Fix options:

• Check Apache/PHP error logs for details.
  
• Downgrade PHP to 5.6–7.2 (works best with Sentora).
  
• Long term: consider migrating to an actively maintained panel (ISPConfig, Virtualmin, etc.).
  

Downgrading PHP is usually the quickest solution.

A 500 error on the Sentora panel after reboot is often due to PHP/MySQL compatibility. Sentora 1.0.3 is quite old and not fully compatible with PHP 7.4/MySQL 5.7, since it still calls deprecated MySQL functions.
Options:

1. Downgrade PHP — Sentora 1.0.3 works best with PHP 5.6–7.2.
   
2. Check logs — Look in
   
   Code:

   /var/log/httpd/error_log
   or
   
   Code:

   /var/log/apache2/error.log
   for exact PHP errors.
   
3. Consider upgrade/migration — Sentora hasn’t had major updates in years. Many users migrate to forks like Sentora CE, Froxlor, or Virtualmin which support modern PHP.
   
4. Temporary fix — If you must stay with 1.0.3, install a compatible PHP version via Remi repo and set Apache to use that.
   

Your sites work because they don’t use the outdated functions, but the panel does. Downgrading PHP (or moving to a newer panel) will restore access.
