Footer link

Hey xandria,
This is how it should be in the copyright section of footer

the [nolink] is to remove the kriesi.at link.
Yet your site is showing the shortcode and the php code, meaning there is a conflict somewhere.
Did you happen to edit one of the theme files, perhaps to add some code?
If you did let us know so we can help correct.
If not I suggest to try disabling your plugins. If that resolves the issue, reactivate each one individually until you find the cause.
If that doesn’t help, Try to upload the theme again manually via FTP: https://vimeo.com/67209750 to repair any broken files.

Best regards,
Mike

Hi,
I have repaired your footer.php so the error is gone, I also fixed your quick css, as it was missing a }
I then added your copyright section of footer which included a link, but please note that you should make sure the link is pointing to the right website. If you wish, add the link here and we can adjust it for you.
Also the link color was going to be white, as set by your theme options so I added some css to make it black with this code, so you can see it.

span.copyright a.xandria { color: #000000;}

If you tell us what color you want it, and what on-hover color we can adjust it for you, unless you can do yourself.
Please clear your browser cache and check.

Best regards,
Mike
