Solution to Error 500 after upgrading to WordPress 2.7

After I recently upgraded my blog to the latest version of Wordpress v2.7, I noticed an Error 500 - Internal server error. This seems to be a problem for WordPress blogs which are hosted by 1&1 The solution to the Error 500 - Internal Server error 1. Create a file called "php.ini" in the /wp-admin/ directory of your blog 2. In the file add the text "memory = 20MB" without the quotes This should fix the problem
