After the 5.1 update, I am getting the following error on calirose.com

Uncaught ReferenceError: tinymce is not defined
in wp-includes/js/tinymce/plugins/compat3x/plugin.min.js file

The result is a non-working visual editor. The tabs [visual] and [text] don’t work. The visual editor (if your user profile was lucky enough to be set to that screen before the update) displays the code, only all in white so it appears as a blank editor.

I have tried:

deactivating all plugins, upon which the edit page is 100% blank
adding define(‘CONCATENATE_SCRIPTS’, false); to my config file
reinstalling the 5.1 core
unchecking []disable visual editor at a user level
creating a new user
reinstalling PHP version
toggling htaccess file off and on

I hesitate to change the theme, as I know this will mean hours for me, as the last time I did it I had to rebuild all my sidebars.
I’m not using any caching at this time and I can’t find any tools for this on the host’s cpanel
I use a child theme with a function that calls an extra sidebar and adds an excerpt to my portfolio pages but that’s all it does.

Any ideas for other things I can try?

Thank you!
Amy
