Pro 4.2.2 - Page made with Pro v4.0 is broken


Since the update, cornerstone is broken. I’m getting “TypeError: o is null”. I had the same error on v4.2.0.

Hello @lijecreative,

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 (staging )
  • Admin level username and password (staging )
  • FTP Details (staging )

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


Go give a shot with the credentials I gave you. I disabled all plugins and using now the default pro theme.
I’m having the same error.
It’s a dedicated server, I don’t have issues with memory.

Hi @lijecreative,

It looks like somehow when you updated it didn’t remove the old javascript files from the previous version and that was getting loaded instead of the new files. I’ve reinstalled Pro on your site and it’s working now.

Working great.
