I am attempting to remove (delete) some legacy sidebar widgets but when I do so, I am not able to update (save) the page.

I get the following error:

Any idea what might be causing this?

Thanks.

Hello @Frank19,

Thanks for writing to us.

It might be the issue of plugin conflict or maybe custom CSS/JS. I would suggest you troubleshoot with a few of the common issues before we investigate your settings.

1. Testing for Plugin Conflict
2. CSS/JS Customization
3. Version Compatibility
4. Disabling Cache

If it doesn’t work for you, please share your details in a secure note. Please provide the following details

• WordPress Login URL
• Admin level username and password

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

Thanks
