Re: Can't enable user themes
That file is not there like you think it is:
It’s a 404.
But it might be wordpress interfering with the forums directory since WP is in your webroot.
Strange that it would happen with a static file though.
Triple check that you have
via FTP, make absolutely sure it’s there.
If it is indeed there, download your
.htaccess file in your top directory (where WP is) and post it here.
