I have completely stumped myself. I'm implementing Alex King's WPGrins for a client and got the smilies to show up in the comment area, but can't get them to show up in the admin interface.
The readme file says to insert the code in the quicktags.php file, which should be located in /wp-admin, but all I see is a quicktags.js file and when I try to add the code to the end of that file, the quicktags in the admin interface disappear.
The stupid thing is, I've added them before on my own site and my husband's site, but for some reason tonight I'm drawing a blank!
