# permalink changed causes http500 error

 * Hi,
    I have started to use wordpress one week ago. So far I had added some 20
   posts. Then I decided to change the permalink format. (ther were no adverts to
   not do this once written posts). I changed from “default” to “date and name based”.
   After I hit the “update permalink structure” button, the page refreshed and… 
   nothing. A http 500 error came up and ever since I was not able to open my blog.
   I have uploaded the original options-permalink.php file to the wp-admin directory,
   but there is no change. I can’t get it back to work. Please help me on this. 
   Thank you in advance.

 * there’s likely a problem with the .htaccess file in your wp root directory. i’d
   start by cleaning that out, setting permissions to something like 777, configuring
   permalinks, then setting correct permissions.
