No errors in the nginx or nodebb logs.
No errors in inspector console either other than this which I've seen for other sites.
This page uses the non standard property “zoom”. Consider using calc() in the relevant property values, or using “transform” along with “transform-origin: 0 0”.
If I refresh the page, then it shows up in the nginx access lot. However, nothing is shown in the log when clicking on anything and Reply doesn't do anything either. I had not even tried that until now.
Oddly, I can delete the copy of the posts. As mentioned above, the converter generated two copies of some of the comments in posts. One more thing that's interesting is that I deleted a comment as moderator for example but it still continues to show, grayed out and says '2 out of 2'
It is even stranger that I can configure the board, change settings etc, but only when it comes to moderating posts, or at least, it's all I've noticed so far, it cannot be done.
