Please get a developer to do the speed optimization and the plugin will work fine. * It seems your theme depends on jQuery, so you have to play with the ignore list and probably need to ignore the jquery file. [https://wordpress.org/plugins/fast-velocity-minify/#faq](https://wordpress.org/plugins/fast-velocity-minify/#faq) * As for the error still showing after disabling the plugin, it must be a cache with your site or server. Once you disable any plugin, wordpress doesn’t use it anymore, but some server providers (or if you have a cache plugin), will save a copy of the frontend page and serve it for a while (avoiding too many queries). * On a lot of hosting providers, the default is 15 minutes… but it can be a lot more. Make sure you check, but there must be a purge cache button somewhere either on your wp-admin or the hosting control panel. * Make sure you purge all caches on the site and server, or contact the hosting provider. * Thread Starter [txtfox](https://wordpress.org/support/users/txtfox/) * (@txtfox) * [8 years, 10 months ago](https://wordpress.org/support/topic/jquery-header-error/#post-9354725) * We have done that.

All cache deleted/ * Plugin Author [Raul P.](https://wordpress.org/support/users/alignak/) * (@alignak) * [8 years, 10 months ago](https://wordpress.org/support/topic/jquery-header-error/#post-9354792) * This plugin doesn’t cache the page, only static css and js files. * If you have disable the plugin and when you “view:source” on your browser, you see references to the cache path on uploads/fvm/cache, then it’s definitely a cache issue with the site / server (or your browser). * What is your site url? Have you deleted the FVM plugin completely? What is your site hosting? - This reply was modified 8 years, 10 months ago by [Raul P.](https://wordpress.org/support/users/alignak/). * Thread Starter [txtfox](https://wordpress.org/support/users/txtfox/) * (@txtfox) * [8 years, 10 months ago](https://wordpress.org/support/topic/jquery-header-error/#post-9354915) * Godaddy Prem.

Make sure you say that you deleted a plugin, but wordpress still shows as if it’s there. * Because your wordpress files are cached in memory, they will keep working even if you delete all files on the installation. * Ex: [https://stackoverflow.com/questions/25423814/godaddy-cache-issue-with-wordpress-project](https://stackoverflow.com/questions/25423814/godaddy-cache-issue-with-wordpress-project) Viewing 6 replies - 1 through 6 (of 6 total) The topic ‘Jquery Header Error’ is closed to new replies. * ![](https://ps.w.org/fast-velocity-minify/assets/icon-128x128.jpg?rev=1440946) * [Fast Velocity Minify](https://wordpress.org/plugins/fast-velocity-minify/) * [Support Threads](https://wordpress.org/support/plugin/fast-velocity-minify/) * [Active Topics](https://wordpress.org/support/plugin/fast-velocity-minify/active/) * [Unresolved Topics](https://wordpress.org/support/plugin/fast-velocity-minify/unresolved/) * [Reviews](https://wordpress.org/support/plugin/fast-velocity-minify/reviews/) * 6 replies * 2 participants * Last reply from: [Raul P.](https://wordpress.org/support/users/alignak/) * Last activity: [8 years, 10 months ago](https://wordpress.org/support/topic/jquery-header-error/#post-9355239) * Status: resolved
