Hi Dawn, I had a look to see if this had been reported previously - looks like someone else experienced the same: MDL-74755

As a workaround, you can visit the "Advanced features" section of your site administration and toggle the "Enable accessibility tools" option

Unfortunately any page in the site administration gave me the same error. I was able to resolve it by renaming the "blocks" folder name to "blocksTEMP" to deactivate that plugin. That allowed me to Turn Editing Off. After I turned it off I renamed the folder back to "block".
