I believe with the latest WpForo update there is a conflict with the plugin Import Users which I have used for a long time. Now the backend crashes and a message is delivered:
An error E_ERROR was caused at line 231 of file /.../plugins/wpforo/classes/Cache.php. Message: Uncaught Error: Call to a member function reset() on null in /.../plugins/wpforo/classes/Cache.php:231 Stack trace: #0 /.../plugins/wpforo/includes/functions.php(1823): wpforo\classes\Cache->clean(13496, 'avatar', Array) #1 /.../plugins/wpforo/classes/Members.php(1751): wpforo_clean_cache('avatar', 13496) #2 /.../plugins/wpforo/classes/Members.php(108): wpforo\classes\Members->reset(13496) #3 /.../wp-includes/class-wp-hook.php(310): wpforo\classes\Members->wpforo\classes\{closure}(13496) #4 /.../wp-includes/class-wp-hook.php(332): WP_Hook->apply_filters('', Array) #5 /.../wp-includes/plugin.php(517): WP_Hook->do_action(Array) #6 /.../wp-includes/user.php(1904): do_action('clean_user_cach...', 13496, Object(WP_User)) #7 /.../wp-includes/user.php(2433): clean_user_cache(Object(WP_User)) #8 /
There is also a persistent error in the tools>debug log:
PHP Warning: call_user_func_array() expects parameter 1 to be a valid callback, function 'featured_products_filter_query' not found or invalid function name in /.../wp-includes/class-wp-hook.php on line 308
Could you please investigate as soon as possible? Thank you
@robert thank you for the prompt correction, I confirm it works now.
I got a little error (as if some users were not imported) but I guess it's because of the previous bug, since the database has stored them correctly under wpforo_profiles.
I will come back here if any future attempts of importing users should fail. cheers
