I've just finished migrating and upgrading my mediawiki server from 1.8.2 to 1.13.2. I also migrated it to another server so I have the old version to refer to if needed. I got a complaint today that there was a page missing. I checked it and it just comes up completely blank with no 404 error or permissions error or anything like that. Its just a blank page.
After Platonides' suggestion, try adding &action=edit to the end of the blank pages' URL. Then visually scan the page for bad syntax. I have to do this all the time since my users forget to close tags from extensions and stuff like that.
