Hi @twistsd
Could you please let me know if you are able to edit wp-config.php file?
In such case I assume that some plugin is not compatible with your current PHP version, if you’re using PHP 8 or 8.1, try to switch back to PHP 7.4. Many plugins in WP Directory does not support PHP 8+ yet.
The easiest way to find out what causes the issue is to enable WP_DEBUG and WP_DEBUG_DISPLAY constant in your wp-config.php file.
Once you enable these two constants, it will display detailed error of what happened on the site, and point you to the plugin which causes the issue.
More details: https://www.ads-software.com/documentation/article/debugging-in-wordpress/#wp_debug_display
– Set both of these constants to TRUE.
Let me know if that gives you more details, it will also allow us to prevent such things in future ??
Thank you!
