You can try./nodebb reset -p <plugin name>
plugin page loading non-stop
We got a fresh install of nodeBB 1.13.2
We activate/install the search plugin nodebb-plugin-dbsearch and nodebb-plugin-modmin and both plugin are giving us a loading circle at the right side and never display something.
have you re-indexed your content? You can click DB search under "Plugin" in Admin Control Panel for this option...
We had similar problems, fixed it this way...
