    Lately we’ve been getting an error after saving pages, “There has been a critical error on this website.” However the change to pages seems to be happening fine. This is the information in the debug log:

    [25-Oct-2024 13:17:51 UTC] PHP Fatal error: Uncaught TypeError: explode(): Argument #2 ($string) must be of type string, array given in /public_html/wp-content/plugins/wp-last-modified-info/inc/Core/Notification.php:114

    Stack trace:

    thrown in /public_html/wp-content/plugins/wp-last-modified-info/inc/Core/Notification.php on line 114

    Deactivating this plugin eliminates the problem. WordPress version 6.6.2, but the problem has been the same with a few earlier incremental releases too.
