WordPress Speed Up Service | WordPress Website Maintenance Packages Reply To: My WP website shows “Fatal error” !, by Keith The error message is telling us that the Payfort plugin is causing an error. Class ‘WC_Payment_Gateway’ not found This most likely indicates a programming error as it is not able to locate a piece of code. The plugin page indicates that this plugin has a small user base and has not been updated in a while. Maybe you can try and contact the developers in the plugins’s dedicated support page here: https://wordpress.org/support/plugin/payfort *after writing this reply, I see others are experiencing the same issue as per the plugins support page.
