Okay. Not sure what triggered this. Everything was fine - been running a functional vanilla forum for a good few months now.
The last thing I did was to enter a new (clear text) password for a user that had forgotten hers via a MySQL manager (direct to database). Checked the site immediately after that, and no probs. Just went back to it, and got the followng errors:
Top of page (source view):

Bottom of page (source view):

The user in question had entered a message once, but didn't see any of the error messages I'm seeing now. The message posted succesfully. I've logged out and logged back in - still greeted by error messages on every page. Freaking me out! Can't figure out what's gone wrong here, or where to fix it...
I couldn't find much on a quick google, but it is definitely a server / php error caused by the attempt of reading or writing session data to a tmp folder on your server. It could be permissions problems on the server (likely) or that you've run out of space in the tmp folder (unlikely). Either way you should contact your hosting provider about it.
I had the same issue yesterday, I'm using custom php.ini and hosting company was changing hdds, so they updated their php, but never mailed me to do same with mine. ask your host, they are changing something.
Mmhmmm. Seems my host had a problem with the fileserver I'm on. Currently deploying an alternative fileserver. In the meantime, status of many services is "Unknown". Wish I'd checked that before I got a 404 that said "The requested URL /people.php was not found on this server." - could have saved me a few grey hairs I know I'm going to eventually develop... ;)
Ack. All of my sites are down, as of about 10 minutes ago. Start the clock - let's see how long my guys take to fix the problem... (is it fickle to say that now's probably a good time to look into the host switch I've been thinking about? ;)
