My website sometimes loads blank pages.

Randomly, my website just loads blank pages. I'm sure if you browse my site for long enough you will find this happen.

Is this a server issue, or something on vBulletin?

Hard to know what the issue is. Take a look at your error_logs (if you don't know where they are, ask your host). They should have some info in them. Also, take a look at the page about blank or white pages - http://www.vbulletin.com/docs/html/blank_pages
