Security Alert. Theme file showing FULL server path

Oh sorry, I forgot: XXX

However there is no problem when you watch the site,
the alert only shows up on the security scanner.

Edit: Link removed due to 113 malicious code upload attempts
in the last hour. Folks… this is a help forum, go play somewhere else.

Thanks for your time
