Hello when i try to login to my site this error shows:
Fatal error : Uncaught Error: Using $this when not in object context in /home/customer/www/aquantum.gr/public_html/wp-content/mu-plugins/plf-filter.php:128 Stack trace: #0 /home/customer/www/aquantum.gr/public_html/wp-includes/class-wp-hook.php(289): Plf_filter::active_plugins(false) #1 /home/customer/www/aquantum.gr/public_html/wp-includes/plugin.php(206): WP_Hook->apply_filters(false, Array) #2 /home/customer/www/aquantum.gr/public_html/wp-includes/option.php(81): apply_filters(‘pre_option_acti…’, false, ‘active_plugins’, Array) #3 /home/customer/www/aquantum.gr/public_html/wp-admin/includes/plugin.php(532): get_option(‘active_plugins’, Array) #4 /home/customer/www/aquantum.gr/public_html/wp-content/themes/x/framework/functions/updates/class-tgm-plugin-activation.php(1828): is_plugin_active(‘advanced-custom…’) #5 /home/customer/www/aquantum.gr/public_html/wp-content/themes/x/framework/functions/updates/class-tgm-plugin-activation.php(1796): TGM_Plugin_Activation->is_plugin_active(‘advanced-custom…’) #6 /home/custom in /home/customer/www/aquantum.gr/public_html/wp-content/mu-plugins/plf-filter.php on line 128
edit I found that the problem was the plugin load filter, when is updated to version 4 it crashes the login and cannot login.
