WordPress updated to 6.0.2, and I have a plugin in some sites that I use to create a photo gallery, its Gallery By Supsystic. Since the last update, every site that I have with this plugin installed do not open. It shows the following message
​
Fatal error: Uncaught Error: Class “Rsc\_Mvc\_Module” not found in /home/solteiro/public\_html/wp-content/plugins/gallery-by-supsystic/src/GridGallery/Featuredplugins/Module.php:4 Stack trace: #0 /home/solteiro/public\_html/wp-content/plugins/gallery-by-supsystic/vendor/Rsc/ClassLoader.php(118): require\_once() #1 /home/solteiro/public\_html/wp-content/plugins/gallery-by-supsystic/vendor/Rsc/Resolver.php(314): RscSgg\_ClassLoader->load() #2 /home/solteiro/public\_html/wp-content/plugins/gallery-by-supsystic/vendor/Rsc/Resolver.php(276): RscSgg\_Resolver->findModules() #3 /home/solteiro/public\_html/wp-content/plugins/gallery-by-supsystic/vendor/Rsc/Resolver.php(82): RscSgg\_Resolver->getModulesList() #4 /home/solteiro/public\_html/wp-includes/class-wp-hook.php(307): RscSgg\_Resolver->install() #5 /home/solteiro/public\_html/wp-includes/class-wp-hook.php(331): WP\_Hook->apply\_filters() #6 /home/solteiro/public\_html/wp-includes/plugin.php(476): WP\_Hook->do\_action() #7 /home/solteiro/public\_html/wp-admin/plugins.php(194): do\_action() #8 {main} thrown in /home/solteiro/public\_html/wp-content/plugins/gallery-by-supsystic/src/GridGallery/Featuredplugins/Module.php on line 4

Can someone help me please? I really don’t know what to do.

Have you tried contacting the developer of the plugin for assistance?
What version of php are you on? If less than 7- try 7.4 or even 8.
Make sure you have sufficient php resources (384M+ ram, 5000+ input_vars).
