I’m also experiencing this mobile menu not working on a site issue. No Wordfence.
Site: https://spahollywood.com/
Console Errors:
Host: WPEngine
Troubleshooting Steps:
Deactivated all plugins except cornerstone - Problem still existed
Switched to Twenty Seventeen theme - Problem does not exist
All WP/plugins/themes up to date
All cache cleared (Browser, server, cdn, etc.)
Downloaded a fresh copy of the theme and deleted x.js and uploaded a new copy. Same error exists.
commented out all custom CSS - No change.
I have a feeling it has something to do with the “Uncaught TypeError: Cannot read property ‘action’ of undefined” But I have no Idea how to fix it.
