I have tried a few times using different browsers and different computers.
Cleared cache. Logged out, logged in, tried the things mentioned on the failure message.
When I select CP then Signature I get a failure message.
I first noticed the problem about 5 days ago,
I just noticed the thread by "Skidlid", same issue..
Thanks for reporting this. I was able to bring that up as well, and have sent a ticket to tech: 2490864
I got the same error when trying to reply to a pm.. Free site is known to be buggy as hell..
I'm on the latest an greatest Enterprise system with no restrictions, lol..
I tried to find this one as well, however I am not seeing any issues when replying to PMs. Is the error you see the same as the one posted above? If so, is there also a yellow box on the page with MySQL information, and can you copy that over to us please?
If it's a different error page, or there is no yellow box with additional information, we'll need some more information for additional troubleshooting:
What browser are you using? Is it up to date?
Do you have any add-ons/extensions running?
Do you have any adblock or noscript programs running?
