Thanks for the prompt reply,
Hmm - this is weird.
I was already running cornerstone at 3.0.4
I've tried clicking on Revoke Validation, but all that does is ad a # at the end of the url
I've Deactivated all plugins - in case these were causing the problem, but the problem persists. Tried different browsers as well, in case it's a cache thing,
Ahh - just checked other sites I'm running X on ( I have several Licenses) - All are behaving in the same manner, even ones I haven't updated yet ( checked on one running X- 4.6.2, and another X-5.2.4 )
Sooooo, server side thingy (excuse the less than technical terminology!)
Any further suggestions?
