Classic Accordion Stopped Working

Hi, I updated today Cornerstone plugin and now my Classic accordion isn't working.

Please, help

Hi There,

Thank you for writing in, you updated the Cornerstone to the latest version (v3.1.3) but not the X. Please update the X to the latest version too (v6.1.3)

Updating Your Themes and Plugins

Remember to clear all caches (plugin, server-side, CDN, and browser's cache) after updating so that the code from the latest release is always in use. This will help you to avoid any potential errors.

Let us know how it goes,


That worked.

Now I can't find the custom css I added to the Customize. Everything changed now and I don't see that option anymore. All I see is the Additional css, but it doesn't have all the css I added. Please help, it is frustrating as I'm wasting a lot of time on these small things.


Hey @psylist,

The Customizer is now discontinued. Please use X > Theme Options from now on. For more details, please see
