Thanks for your reply. Hmm, it worked for months, perhaps even a year, since I last upgraded. My access to free upgrades has been over for quite a long time, I believe. Yes, almost exactly a year ago. I'm running 6.6.1.
There's no fix or service patch? It's odd that this would start happening out of nowhere, or is that known behavior for this bug? It would seem a shame if I have to pay $100 to fix a serious bug! That's what's member area access to get 6.7 would cost, no?
If there's a hack or some coding I can do to work around or fix this bug I'm willing to do it.
