Hey chodges1969. Are you experiencing this issue in firefox? Or is it another browser? We have determined the issue seems to be firefox specific, but if it is happening for you in another browser please let me know version if you could! I am working on patching this now.
My response in the other thread follows:
Hey gang. Apologies again. Looks like the issue came through in the minifier (google closure compiler). Until we get the hotfix out you can try adding
to your wp-config file. This should fix the issue until we get the hotfix out as it loads the unminified files. Please be aware that constant does also cause wp to load unminified files in the admin for the core js and css though, so its up to you whether or not you are ok with that.
Will update this thread as soon as we get the fix out, at which point you can remove/set false this line.
