A few weeks ago I ran into an issue with my web host that made me a little frustrated. Here's what was happening.

When creating a simple blog post with pictures and a bulleted list would send me to a blank page with a "page not found" error. I was a little confused with this, and wasn't really sure where to even start. The first place I checked was my watchdog log in Drupal. The only thing that it showed was the page not found error and it showed that I was trying to access a page called "500.shtml." When I ran into this a problem a while ago I decided to just modify my post and remove most of the html so that it would go through. This time there was no way around it.
