Title: ReferenceError: jQuery is not defined Last modified: August 20, 2016 --- # ReferenceError: jQuery is not defined * [dontstop99](https://wordpress.org/support/users/dontstop99/) * (@dontstop99) * [14 years ago](https://wordpress.org/support/topic/referenceerror-jquery-is-not-defined/) * I am unable to add images or edit widgets or edit slugs or even change accessibility options by clicking on ‘screen options’. * Basically nothing happens when I click. Even changing the theme to Twenty eleven does not solve the problem. I am using WPZOOM’s MONOGRAPH THEME. * All this works fine with IE7. * In console I see this error- ReferenceError: jQuery is not defined * I have been stuck with issue for about a week and I have tried everything including WP re-install. * I think a lot of people are affected by this issue/WP bug and WP support should do something about it.

If this works, re-activate the plugins one by one until you find the problematic plugin(s). * – switching to the Twenty Eleven theme to rule out any theme-specific problems. * – [resetting the plugins folder](http://codex.wordpress.org/FAQ_Troubleshooting#How_to_deactivate_all_plugins_when_not_able_to_access_the_administrative_menus.3F) by FTP or PhpMyAdmin. Sometimes, an apparently inactive plugin can still cause problems. * – re-uploading the wp-admin and wp-includes folders from a **fresh** download of WordPress. * There is no known issue in WordPress 3.3 of this type. * Thread Starter [dontstop99](https://wordpress.org/support/users/dontstop99/) * (@dontstop99) * [14 years ago](https://wordpress.org/support/topic/referenceerror-jquery-is-not-defined/#post-2705091) * I have tried * – Deactivating all plugin process * – switching to the Twenty Eleven theme * – re-installing WP (same as re-uploading the wp-admin and wp-includes ) * – resetting the plugins folder * None of these worked. * I am using 3.3.2 * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [14 years ago](https://wordpress.org/support/topic/referenceerror-jquery-is-not-defined/#post-2705227) * Site url? * Thread Starter [dontstop99](https://wordpress.org/support/users/dontstop99/) * (@dontstop99) * [14 years ago](https://wordpress.org/support/topic/referenceerror-jquery-is-not-defined/#post-2705251) * Its [http://is.gd/X5luwM](http://is.gd/X5luwM) * [esmi](https://wordpress.org/support/users/esmi/) * (@esmi) * [14 years ago](https://wordpress.org/support/topic/referenceerror-jquery-is-not-defined/#post-2705270) * Can we see the site using Twenty Eleven with no plugin active? * Thread Starter [dontstop99](https://wordpress.org/support/users/dontstop99/) * (@dontstop99) * [14 years ago](https://wordpress.org/support/topic/referenceerror-jquery-is-not-defined/#post-2705297) * I have checked its not working. * Its a live site so it would be difficult to change the theme.
