 * Hi,
 * I get tons of JavaScript errors in my WordPress Backend using the Yoast SEO plugin.
 * [JavaScript Console](https://www.dropbox.com/s/dhh08ruahpddudq/Screenshot_2017-08-28-12%3A19%3A17-1.png?dl=0)
 * I’m not sure where to begin to solve these issues. This also blocks some options
   for my theme (which is based on Gantry btw), I need to disable Yoast SEO to use
   JavaScript features in the backend.

 * Can you please make sure you’re running the latest version of WordPress 4.8.1,
   Yoast SEO 5.3.2 and your theme?
 * If you are already up-to-date, please check if the problem is still the same 
   when all non-Yoast plugins are deactivated _and_ your active theme is on [Twenty Seventeen](https://wordpress.org/themes/twentyseventeen/)?
 * If you are unfamiliar with checking for conflicts, we wrote a small guide that
   will walk you through the steps. You can find it here: [How to Check For Plugin Conflicts](https://kb.yoast.com/kb/how-to-check-for-plugin-conflicts/)

 * I think it’s a problem with Gantry. I found the issue here:
    [http://www.rockettheme.com/forum/configuration-and-security/270064-yoast-seo-stopped-working?start=0#1359916](http://www.rockettheme.com/forum/configuration-and-security/270064-yoast-seo-stopped-working?start=0#1359916)
 * It seems to be a problem with mootools. If I remove mootools, YoastSEO seems 
   to work

 * There’s indeed a conflict between (old versions of) MooTools and Yoast SEO. You
   can find additional information in this KB article: [https://kb.yoast.com/kb/conflict-rokcommon-library-roksprocket/](https://kb.yoast.com/kb/conflict-rokcommon-library-roksprocket/)
   Unfortunately, there’s nothing we can do to fix this.

 * There was a new release of Gantry today which fixes issues for the Gantry related
   pages: [https://wordpress.org/support/topic/conflict-with-yoast-seo-24/](https://wordpress.org/support/topic/conflict-with-yoast-seo-24/)
 * But Yoast SEO itself isn’t working yet. Is there a way to remove mootools from
   some backend pages (like posts)?

 * The Yoast plugin does not use Mootools, so there must be some other plugin causing
   the conflict. You can check for conflicts to find which plugin is causing this.

 * Yes, it’s caused by RokSprocket from Rocket Theme.
