License crediting issues

The following templates under the CC BY 3.0 license don’t have a footer with credits:

The official license terms state that I have to credit the owner if it doesn’t fall under fair use but the license information page on Colorlib only states that I can’t remove existing credits.
Do I:

  1. Have to add a credit footer myself
  2. Can I just link to another page with credits
  3. Can I use these templates without credits

hey there

You may add-footer credits yourself, if you have any problem with his I can help :slight_smile:
