What exactly is the critical error? You should receive an email from your WP site indicating the nature and description of the error.
An error of type E_ERROR was caused in line 721 of the file /home/sitename/webapps/sitename/wp-content/plugins/user-switching/user-switching.php. Error message: Uncaught TypeError: Argument 1 passed to user_switching::filter_removable_query_args() must be of the type array, null given, called in /home/sitename/webapps/sitename/wp-includes/class-wp-hook.php on line 287 and defined in /home/sitename/webapps/sitename/wp-content/plugins/user-switching/user-switching.php:721
Yeah looking at those errors, it is something that is happening on the “user-switching” plugin side of things. There is not much I can do about it from the BH side. Best advice is to report the error to the user-switching developers, they will know best how to resolve the issue. Let me know if I can provide any further infos about Banhammer, glad to help anytime.
Banhammer is returning an invalid value from its removable_query_args filter.
See https://developer.wordpress.org/reference/hooks/removable_query_args/. null is not an allowed return value for this filter.
Ah, thank you. Will change it to return an empty array instead.
Just to follow up, this issue is resolved in the next version of Banhammer. Should be released today or tomorrow. Thanks @holisticmissions and @johnbillion.
