Tnx for your replies. I have tried to add a /# to the link but even though the link shows briefly, it keeps bouncing back and forth after a few seconds. I tried various browsers. Same result.
Only plugins used are WPforms and also tried to edit the site with Elementor but to no avail.
Here the WPforms link [wpforms id=”48″ title=”false” description=”false”]. Hence I have also tried to remove the link. No changes.
I am running on empty here as far as possible solutions. No clue anymore, what goes wrong here. Any further ideas are highly appreciated.
