    Good morning

    Some of our clients are experiencing problems with their web sites

    As soon as we update the plugin and they have the supsystic slider or gallery

    The entire site the does not work and I get a debugging message

    The 3 so far are the following domains: – Real Estae template – Perfect Photography – Picart

    Example of one of the errors:

    1.Since WordPress 5.2 there is a built-in feature that detects when a plugin or theme causes a fatal error on your site, and notifies you with this automated email.

    In this case, WordPress caught an error with one of your plugins, Membership by Supsystic.

    First, visit your website ( and check for any visible issues. Next, visit the page where the error was caught ( and check for any visible issues.

    2.Upon checking the error message on the website and after enabling the displaying of PHP errors, I found that the following error was displayed:

    Fatal error: Uncaught Error: Class ‘Twig_SimpleFunction’ not found in /usr/www/users/stilbo/wp-content/plugins/slider-by-supsystic/src/SupsysticSlider/Core/Module.php:107 Stack trace: #0 /usr/www/users/stilbo/wp-content/plugins/slider-by-supsystic/src/SupsysticSlider/Core/Module.php(26): SupsysticSlider_Core_Module->registerTwigFunctions() #1 /usr/www/users/stilbo/wp-content/plugins/gallery-by-supsystic/vendor/Rsc/Resolver.php(103): SupsysticSlider_Core_Module->onInit() #2 /usr/www/users/stilbo/wp-content/plugins/gallery-by-supsystic/vendor/Rsc/Environment.php(244): Rsc_Resolver->init() #3 /usr/www/users/stilbo/wp-includes/class-wp-hook.php(287): Rsc_Environment->extend(”) #4 /usr/www/users/stilbo/wp-includes/class-wp-hook.php(311): WP_Hook->apply_filters(NULL, Array) #5 /usr/www/users/stilbo/wp-includes/plugin.php(478): WP_Hook->do_action(Array) #6 /usr/www/users/stilbo/wp-settings.php(403): do_action(‘plugins_loaded’) #7 /usr/www/users/stilbo/wp-config.php(46): require_once(‘/usr/www/users/…’) #8 /usr/www/users/stilb in /usr/www/users/stilbo/wp-content/plugins/slider-by-supsystic/src/SupsysticSlider/Core/Module.php on line 107

    This would appear to indicate that a plugin is not compatible with the latest version of PHP or may perhaps need to be replaced.

    Can you please assist

    Kindly add this code in core-functions.php at top of //CONTENT WIDTH line number 14 and check out the error

    ini_set('error_reporting', E_ALL );
