For those who don't want to read the article, he said the error was being caused by having the <compilation debug="true"> and that changing it to false fixes it. There were other comments stating that a slow server could cause this as well.

 

This did not fix it for me. Debug is set to false and I am still getting the same error. I will try it on my other pc and on a web server to see what happens there. I will send an update once I can get some time to try it out.
