   So, I added add_theme_support('post-thumbnails'); to the functions.php of my theme, and now I can't access any part of my site. Every page just says:

   Fatal error: Call to undefined function the_post_thumbnail() in /home/themsssc/public_html/frontline/wp-content/themes/grisaille/functions.php on line 16

   Any help would be appreciated!

   Go in functions.php and delete that code.
   Simple as that :)

   And you have lots of plugins for thumbnails.
   Search for them.
   Its easier than you manually adding codes.

   I can't go to the functions.php because I can no longer log in to my site.

   Every page just comes up with the error message!

   Download some free FTP client. Or addon for browser like FireFTP for firefox.
   Connect using your FTP details
   Find this file
   /public_html/frontline/wp-content/themes/grisaille/functions.php
   Download to your computer
   Edit
   Upload file back
