The secondary sidebar of my website (www.drachenwolke.com) is no longer displayd on the right side, but has moved to the bottom.
Recently I have updated to wordpress 5.8 (sidebar blogs) and php 8.0. With this update the problem has emerged.
I had already disabled all plugins, which did not bring any change. The settings of the website are unchanged. A check with the Health Check plugin shows no problems.
How can get the right sidebar back to the intended place? Is there perhaps a compability problem with WP 5.8? Is this a known problem?
