Like server log files, BugMonitor displays PHP errors and warnings, showing the details of the error, including the file where it occurred. BugMonitor also reveals whether a specific plugin or theme is involved in the error. Thus, the problem can be managed even without code correction.
Solution:
A PHP warning is a minor error that does not stop the site from functioning but can cause problems, so it’s worth paying attention to these as well. If the site’s functionality is not affected, it may be sufficient to simply report the error to the developer for correction in a future update.
A Fatal error is an issue that prevents the site from functioning. These must be temporarily resolved until the developer can permanently fix them. The cause might be a plugin conflict or a simple code error. Of course, these errors should also be reported to the developer, but try to resolve them in the meantime.
1.) If the error occurred after an update, revert to the previous version. If you have a backup, you can restore the state before the update. Alternatively, you can use the WP Rollback plugin to revert update for a plugin.
2.) If the error appeared after installing a new plugin, deactivate the new plugin until the developers resolve the issue.It is recommended to inform both plugin developers about the conflict for a proper and quick fix.
3.) It's possible that a plugin or the theme is not compatible with the PHP version. Therefore, if the error occurs after changing PHP versions, temporarily revert to the previous version until the issue is fixed.
4.) Insufficient memory (allowed memory size exhausted) often causes problems. This can be easily fixed by increasing the memory limit in the wp-config.php file
define('WP_MEMORY_LIMIT', '256M');
