Hoffe das passt so

Vielen Dank für die Antwort. Ich hatte mich jetzt dazu entschieden, WP neu aufzusetzen. Ich hatte eine Frische Backup Kopie von gestern, weshalb ich nicht so viel verloren habe. Aber das ist natürlich eine Gute Idee 🙂

Ist es denn Grundsätzlich möglich das ein ein 500er Fehler kommt aufgrund von Yoast SEO?

Aber ich denke dann hat sich das Thema oben gegessen 🙂 Daher immer schön Backups machen 🙂

Vielen Dank für die Hilfe. Ich denke ich werde eh wieder mal ein Problem haben, spätestens dann hört Ihr wieder was von mir 🙂
