Everytime I go to a category and I get the message my nodebb is disconnected. If i'm going to another page it connects again.
I have this problem since I upgraded to 1.6.1 does somebody have the same problem?
Found the problem. it was the plugin nodebb-plugin-merge-subtopics
It could load any category page with sub-categories in it.
Maybe it's hepfull for somebody who has same problem
