I have the same problem with AJAX forms. The form will load when I'm logged in, but it's showing the loading icon and message forever for my visitors / non-login users. I can't see anything in debug log too. I have to disable AJAX forms for the timebeing.
I think you just forgot to include the proper require_js() in your skin header. Please compare the JS loaded by a default skin with the JS loaded by your custom skin.
That was it. _html_header.inc.php had not been updated in my skin folder. Merci!
Turn on the AJAX Debug log and see what goes wrong:
