I have set a static homepage in my settings. After upgrading my php version from 7.4 to 8.0 the homepage displays my latest post instead of the selected static page.
Deactivating all plugins and switching to default theme did not help, under all circumstances all I got was the latest post, not my homepage. It was not accessible at all.
After reverting to WordPress 6.1 everything worked fine. Also after reverting to php 7.4. So there appears to be something terribly wrong with ClassicPress’ php 8 support. Of am I missing something?
