There are still major problems with this installation/upgrade. Some posts go through immediately, others hang once you click submit and this error comes up:
This site can’t be reached
The webpage at http://gtworld.ca/posting.php?mode=reply&f=16&t=1410
might be temporarily down or it may have moved permanently to a new web address.
Member activations ALWAYS hang but deleting a registration never hangs. The activations are completed but there is no verification page. Once you open the forum in another tab, you see the member has been activated. I get this error now (new) when activating:

I'm lost as to where to go now. If I can't find a solution here, what are my options? I now have 1500 members so I feel an enormous responsibility to them. Any solutions, suggestions, whatever would be appreciated. Thanks!
