 * When I try and activate certain plugins, I get the following fatal error:
 * “Fatal error: Cannot redeclare write_post() (previously declared in ..//wp-admin/
   admin-functions.php:4) in ../wp-admin/admin-functions.php on line 3″
 * Any ideas on how to solve this? I’ve tried everything.
 * Thanks in advance,
 * Tom

 * In these plugins the file /wp-admin/admin-functions.php is probably called through
   an include or require command. Change this to an include_once or require_once
   command. Click [here](http://www.somecoders.com/2006/06/the-difference-between-include-and-include_once/)
   for more info on this.

 * Thanks, but it was already a required_once command.
 * Any other suggestions?

 * Comment out the line with the require in it, and see if it works. (it is a longshot
   btw)
 * **edit:** Forget that, look [over here](http://www.bos89.nl/1212).
