Copyright line cut

Hi there,

I put this in the field Copyright Line:

© 2015. All Rights Reserved. | Imprint | Terms and Conditions | Privacy Policy

After saving the changes, the copyright line appears fine on the bottom of the site.

However, a short time later, the copyright line is magically cut down to

© 2015. All Rights Reserved. | <a title=„Imprint“ href=

For example please see

Why is that?
