Works like a charm now. Thanks for the quick fix!
I can't seem to edit a deck guide I created for a Runeterra deck (https://outof.cards/legends-of-runeterra/decks/271-fiora-barrier).
I can change the text by clicking "Edit Guide", but after saving, the text on the deck page is unchanged. The changes seem to be saved for the editing page only, because when I click "Edit Guide" again, the changes are there.
