Amarok It gets difficult because if you don’t clear cache every time you might still see the error even if the problem extension isn’t activated.
Most BBCode extensions have not had to be updated in a while because they’ve been compatible since beta 8 I think without having to change much. In other words, usually they are pretty stable and so I would bet that it is Drafts or Profile Cover. But, hard to say. 🤷♂️
