Moved site - question on 500 error

[محروم.كوم]

We recently transferred servers and now have been getting a few problems* been looking in error logs and see this one.

[Wed Nov 25 14:46:43 2009] [error] [client xx.xxx.xxx.xx] File does not exist: /home/xxxxxx/public_html/500.shtml* referer: http://xxxxxxxxxxxx.com/forum/login....b84a3d851cb5c3


We are having about a third of our members saying they cant log in yet at the same time others log in and out with no problem. What does the above refer to for a lame brain which is me todya?
