Recently I've been coming across articles on my Wiki that have been blanked out. Thinking it was vandals, I went into the article's history to undo whoever erased the page. But then I see that the history doesn't show anyone erasing the article. Upon entering Edit, I saw that the article does indeed have all the content, but for some reason it's not showing.

According to someone from the CreepyPasta Wiki this appears to be a Wikia-wide phenomenon that's not exclusive to any one Wiki.

So my question is what causes this and how can I prevent it? It's very annoying to have to screen through articles to make sure they're not showing up blank, especially since there's no way to tell if an article has randomly gone blank.
