All of sudden, one of my wordpress sites breaks and outputs this when I go in to add/edit a post

Error 500 - Internal server error An internal server error has occured! Please try again later.

What can I do?

There's not nearly enough information here to answer this question. Many things can cause 500 errors; most of them would fall under "too localized". – Chip Bennett Feb 15 '12 at 14:26

This Kind of problem is something you need to check step by step..

First:

  1. Connect to your hosting with an ftp software
  2. delete your .htaccess file
  3. Log in to your admin and choose default permalink structure (just temporary) (thats in settings > permalink).. SAve your Changes &...
  4. Try to create a new post now.

Didnt help?
5. Try while still logged in to you website host to change the 'plugin' name (temporary).. i know there some weird bugs sometimes like in "Ultimate Plugins Smart Update Pinger (version 3.0)" or in otheres...

If you change the name of your plugin directory and that solves the problem you can now go plugin by plugin activating / deActivating them to check which one is the problem.

As a last resort
I would also verify that your server offer php5+ cuz php4 can cause that problem to.

Hope this helps :)
