Funny errors with Vbulletein

High I run an IT/webmaster forum using VBulletein. I am having an issue where when I edit a post I start getting loading errors, such as missing images in the header and other places. I aslo receive a 404 error sometimes but not after refreshing the page. I am sure its an issue with the hosting server as after its starts happening it isn't limited to this site only but also other sites I have hosted on the same server. The problem will last for a few hours and then clear up, only to return each time I edit a post. I am totaly confused. Has anyone had experience with this or have any advice they can suggest. - Thanks in advance -

 

who's your host ? have you emailed them and asked support.

 

Ya I have talked with em about it to no resolve though, I'd rather not mention there name.

 

I'd say guys at vBulletin.org are the best people to ask for a clue to this problem. I've had vBulletin troubles in the past and sometimes it turned out to be bugs while other times issues were caused by database server problems.
