@angelika: danke, ein php-Downgrade auf 7.4.20 scheint das Problem zu lösen. Zumindest erhalte ich keine fatal errors mehr.
Aber eigentlich schade, weil php 8.0 doch eine deutlich gesteigerte Performance bietet…
Das Spannende an der Sache ist. Das Plugin Health Check liefert auch in php 8.0 keine Fehler. Und – was mich schon ein wenig irritiert – gibt für sich selbst eine höchste unterstützte php-Version von 5.6 an [sic!]. Also das macht mich schon ein wenig skeptisch, was die Qualität des Plugins betrifft?!
