Just yesterday, I brought www.caldems.com into version 3.0 of WordPress, and everything was working without any problems. Well, today to my surprise I started getting “internal server errors” from 1and1, our host:

“Error 500 – Internal server error

An internal server error has occurred! Please try again later.”

Well, to those getting this error message, the fix is simple. Just place a file named “php.ini” (without the quotes) into your ~/wp-admin directory, and within the file, drop this one line of code:

Memory=40MB

This file dictates how much memory you will be allocating to your WordPress installation. After that, your WordPress isntallation should start working again!
