I have been getting emails today with similar error messages as posted above. This error problem started this morning with this error above being the first and during the rest of the day I have had another 12 errors since.

No idea where to even start looking to fix it?

No updates have been added to the site in quite some time. A site back up was done # 21 days ago. It's just been business as usual until today.

Thanks

I searched the site and none of the error message IP's belong to registered users. Some of the error message do come from repeat IP's.

check servername, port, username, password in config

Like I posted...everything is correct. Thanks

Here is what I was suspicious of though. FORUM RUNNER

I have been having troubles with Forum Runner on my Iphone and getting a lot of server errors and time outs. Too bad I opted not to rate Forum Runner soon after I received my Iphone 5......live and learn.

So I looked into some more IP's from people I know that are using Forum Runner and it seems that they are coming up in the IP's for their providers in the same locations.

I need to address this on the other site now it seems.

Thanks

If all your information is correct, then you should contact your host about it.
