Hi Malcolm,
Thanks for updating your theme to the latest version. I see the issue is still persist. To isolate the issue, please follow the guidelines below.
- If you’re using a child theme, you need to switch to your parent theme to see if your child theme customizations are causing this issue. In case if you don’t have child theme, but if you have added any customizations directly to the parent theme also needs to check.
- Remove your custom JavaScript and test this issue further.
- Disable all of your 3rd party plugins except Cornerstone and re-test this issue to see if one of your plugins causing this issue. If the issue is resolved, you can then activate your plugins one by one to see which plugin causing this issue.
Let us know how it goes.
Thanks!
