Critical Error when loading Plugin Settings Page
-
On one of my websites I get an internal server error when trying to access the admin settings page for the Justified Gallery plugin. The page does not load and the following WordPress error message appears: “There has been a critical error on this website. Please check your site admin email inbox for instructions.” All other pages and the front-end galleries are still loading perfectly without any errors.
I tried disabling other plugins to see if there was a compatibility issue. When I disabled “Smart Slider 3” by Nextend the Justified Gallery settings page loaded without showing an error, but only the header and the 3 page tabs appeared while the contents of the tabs was still missing. The settings page used to load fine in the past but I haven’t looked at it for a few months so am not sure if there was any specific update which caused the issue.
I tried to replicate the issue on a second website by installing both plugins, but am not able to reproduce the error. Do you have any ideas what could be causing this issue, or suggestions of how to narrow it down further?
Here is some information about my setup:
- WordPress Version: 6.1.1
- Php Version: 8.1.0 (recently updated)
- Justified Gallery Version: 1.7.3
- Smart Slider 3 Version: 3.5.1.14
