Thank you for the answer.
However, I still could not solve the problem so far. I don’t see anywhere in the shortcode where I could enter a URL or did it with a “#”.
However, I have since determined that is obviously related to a CSS style from another plugin. Unfortunately I can’t find a solution for this either.
If I set in the CSS “pointer-events: none;”, then the link is gone. But of course also the hover property. Unfortunately I’m not so good in own scripting. But maybe there is a tip for me… THANKS!!! Would help me a lot.
