It seems like the package has gone corrupt. Also, please try with a fresh install and let us know regarding the outcome. * If the issue happens again then we need the export file of the plugin to replicate the issue. * Regards, Kriti Viewing 3 replies - 1 through 3 (of 3 total) The topic ‘Fatal error: Uncaught Error: Class’ is closed to new replies. * ![](https://ps.w.org/responsive-menu/assets/icon-256x256.png?rev=1782326) * [Responsive Menu - Create Mobile-Friendly Menu](https://wordpress.org/plugins/responsive-menu/) * [Frequently Asked Questions](https://wordpress.org/plugins/responsive-menu/#faq) * [Support Threads](https://wordpress.org/support/plugin/responsive-menu/) * [Active Topics](https://wordpress.org/support/plugin/responsive-menu/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/responsive-menu/unresolved/) * [Reviews](https://wordpress.org/support/plugin/responsive-menu/reviews/) * 3 replies * 2 participants * Last reply from: [expresstechsupport](https://wordpress.org/support/users/expresstechsupport/) * Last activity: [5 years, 9 months ago](https://wordpress.org/support/topic/fatal-error-uncaught-error-class/#post-13359104) * Status: resolved
