So I am getting this error A LOT. It's mostly when I initially visit my forum. It'll take about 10 seconds or so to load and then that error will pop up. Of course once I refresh it'll load normally as well.

However, my users have also reported seeing this quite a bit as well just from randomly browsing and it pops up for them when they browse forums or threads.

 

The browser tab says "A configuration or Server error has occurred" and this is what it looks like Any help would be appreciated!

 

I would recommend submitting a support request. EX126 is likely a MySQL Error, and probably points to a problem with tmp.
