Ohhh my. I know that sickening feeling. It's akin to losing your cat or dog. Then you wonder if your search engine rankings will be affected. Not to mention what your members are wondering... Your members with whom it is near impossible to communicate with.

I saw where others tried to help. Perhaps they can revisit your case. I would open another thread about it. Then you will be likely noticed.

Hopefully in the future, a cumulative update will be released without delay for those who did not and do not incrementally update.

Don't be discouraged. You did your best to keep your site up and running. The dust will soon settle. Somewhere not far away the solution is out there.
