Mobile Menu Not Working after Updates of X & Cornerstone

I just designed this is a stage site moving to another domain.
After updating I have lost functionality of the mobile menu.
Things I’ve done so far:

  1. deactivated and reactivated plugins
  2. cleared cash in Active X
  3. tried creating a new menu to trouble shoot if it was the menu itself - same issue exists.

Any help would be appreciated here. Would love to go live with this theme.

Hi there,

Thanks for writing in! The issue you’re having is due to the incompatible version of X with Cornerstone as you’re using an old version of X with the latest version of Cornerstone. Always make sure to use the compatible versions and update both X and Cornerstone to latest version to avoid such conflicts and potential errors. You can find the latest version numbers here: ( Then you can compare them to what’s installed on your site.

If you find anything to be out of date, you can review our update guide.

Updating the theme will fix the issue, don’t forget to clear all cache (plugin, browser or CDN) before and after updating the theme.


Hi Nabeel,

Thanks for following up.

I am running Cornerstone 3.04 and X 5.25.

I went to the page you suggested for the latest version numbers which are displayed as
Pro 2.1.0, X 6.1.0, Cornerstone 3.1.0 -

I can’t find where to download the latest version of X and am not sure if the two I’ve stated first above are compatible.

Can you further assist please?


Hi again,

The compatible versions are X 6.0.4 and Cornerstone 3.0.4 you can find the latest version of X and Cornerstone in your Apex dashboard. Also you can automatically update your theme via Dashboard > Updates in your WordPress dashboard, for a complete update guide please see

Hope this helps!
