Ad stopped working

  • Affected Version
    WoltLab Suite 3.1

    An Ad that was properly configured in my forum and worked for years suddenly stopped working. Might have been after some update but I only noticed now so can't say for sure. Below is the script, set to display in the Logo position. The Ad will not even save when I make changes and click submit, instead it redirects me to the forum. I need help to make this work again please.
