 * Fatal error: Call to undefined function get_post_mime_types() in /home/xxxxxx/
   public_html/noonecaresaboutwhatyoudo.com/wp-admin/includes/media.php on line 
   1157
 * that’s what i see when i try to insert the media into my posts. i know they’re
   still uploading because i can see them in media>library, i just can’t use them.
 * i use the theme videographex, just before this happened my friend that does some
   simple coding for me installed the postmash plugin, but he doesn’t think he edited
   anything that would’ve caused this.
 * i really appreciate any help. thanks.

 * Hi,
 * Check the file called “wp-admin\includes\post.php”, you must find a line :
    `
   function get_post_mime_types()`
 * If you don’t find this line, this mean there is no function called “get_post_mime_types”!!!
   Otherwise, try to overwrite the file “wp-admin\includes\post.php” to solve the
   issue.

 * thanks for the quick reply. can you tell me exactly where in the script that 
   line is supposed to go? we haven’t been able to make it work.
