Hi there

I’m running Theme X v.8.1.5 and Cornerstone v.5.1.5

When I try to edit any page, then I get the error “Uncaught (in promise) DOMException: String contains an invalid character” from the file /wp-content/plugins/cornerstone/assets/dist/js/app.f241066.js

Any syggestions?

Hello @inventioweb,

Thanks for writing to us.

It seems that there might be an issue of plugin conflict. I would suggest you troubleshoot with a few of the common issues before we investigate your settings.

  1. Testing For Theme Related Issue
  2. Testing For Plugin Conflict
  3. Theme Update
  4. Child Theme
  5. Css/Js Customization
  6. Increasing Php Memory Limit
  7. Disabling Cache
  8. Disabling Cdn
  9. Permalinks
  10. Version Compatibility

If none of those work, It would be best if you could copying your live website to your staging area. and send your details in a secure note so that we can investigate your setting without breaking your live site. Please provide the following details

  • WordPress Login URL
  • Admin level username and password
  • FTP Details

You can find the Secure Note button at the bottom of your posts

Hi

After a longer deactivate and reactivate plugin session I managed to find the sinner - the Header & Footer Scripts plugin. Thanks!
