Chrome Content Block tinymce issue

I have a few legacy sites that are still running version and 5.6.4 and there is a new issue with what seems to be the latest version of Chrome and the TinyMCE editor.

When adding two or more content blocks to an area a JavaScript error is thrown that is preventing the content from being added to the page. The error is:

Uncaught TypeError: Cannot read property 'body' of null

I was not able to replicate in Firefox so that's why I think it's isolated to a Chrome update. Attached is a screen shot as well. Any help would be GREATLY appreciated.

We've been experiencing this in the last week also, have not found a solution yet.

The issue does not exist in Concrete It appears to be an issue with tinymce.

I'm testing now, but thus far what seems to work is taking:


FROM and replacing this directory in Make sure to backup or make a duplicate prior to replacing. I'm still testing this, but it's working. I'd much rather a "fix" than replacing, but testing thus far there aren't any issues...I'll report back if I find any.

Make sure you clear your cache if you test this...or hold Shift + Reload a few times prior...
