Fatal error in exception handler
I have three sites, and the # 1751255215 is always different as I reset the browser page and different for each site,
I Get this " Fatal error in exception handler. Check log for Exception at time 1751255215 "
The error file at the server said:
[Mon Jun 30 03:46:55 2025] [error] mod_fcgid: stderr: [2025-06-30T03:46:55+00:00] ELGG.ERROR: Exception at time 1751255215:

You must log in to post replies.The number is not telling about the reason for the error. It's a timestamp telling only when the error happened. You need to look into the error log and search for an entry at the time of the error to find out what is happening.
Inside the error log, this is what I got.
The domain's error logs reveal no additional information regarding the error:
[Mon Jun 30 02:45:30 2025] [error] mod_fcgid: stderr: [2025-06-30T02:45:30+00:00] ELGG.ERROR: Exception at time 1751251530:

Thank You.
I suggest you use 'Developer tools' plugin to find the error instead of digging through the error log.
1 - Go to 'Plugins' page and activate 'Developer tools' plugin.
2 - Go to the plugin's settings page /admin/plugin_settings/developers
3 - Select 'Trace level' option and choose 'Log errors and warnings'
4 - Switch on 'Enable error log' option and 'Save' settings
5 - Now reproduce your critical error and check out log on the /admin/develop_tools/error_log page
Nikolai, I can't go to the page because the error doesn't allow me to see the login page. However, if you tell me how to activate that plugin from the server side, I could edit it and maybe get results.
"Fatal error in exception handler. Check log for Exception at time 1751315922 " is all I see from the browser side".
Thank You.
This error was fixed by Optimizing Tables on the website's database. Also, it happened because o high use of memory.
Thank You.
