We had a hardware failure on one of our servers last Sunday. See this thread:
https://forum.oneclickchicks.com/showthread.php?t=147421
Since then we have been working to get things running smoothly, however page loads have been slower when the forums have a lot of member's online due to the fact that our servers have been under a heavy load working to rebuild the data on the server with the failed hard drive. Unfortunately this is time consuming because the forums currently host over 3 Terabytes of material. This should be resolved shortly.
Thanks for understanding.
