I receive this error at random times and random places through out the admin side of my store. It is really annoying and has caused me to lose quite a bit of work. If I click on OK and click again on whatever prompted the error I am able to proceed (with loss of whatever I have done, which did I say is annoying, especially after an hour of formating a product description) Anybody have any ideas?
I have also found that it occurs randomly on the front end end, happened at a test check out. Cant have that.
