There is a bug in the category module (in 0.7). As a temporary solution I had to activate all "inactive" categories (and change the permissions on them to be invisible for the normal registered users).
I have the exact same issue here, on console have the following issue:
Error parsing plugins : Hostname/IP doesn't match certificate's altnames: "Host: packages.nodebb.org. is not in the cert's altnames: DNS:[domain].com, DNS:www.[domain].com"
