Looks like this plugin's development is pretty much dead...
@APXEOLOG, would it be possible to make it usable again?

Right now I'm in the middle of building a fairly big community system, and my users would largely appreciate being able to use BBCodes... I think it's the same for many other people out there.

To be honest, I also think that NodeBB's success is partially dependent on this, as many users refuse to ease into it because of the lack of the tools they've used to know and love, such as the BBCodes themselves

Thanks, I'll try to communicate with the plugins' developers

Since I've updated from v0.7.4 to v0.8.1, a lot of plugins have disappeared from the NodeBB plugin list, "nodebb-plugin-emailer-mailjet" included, which I was using for email dispatch.
Also I remember that the plugin list was at least double of what it is now.

What is the reason behind the disappearance of so many plugins from the "Install Plugins" page?

I see, so at this point it all depends on my implementation of the OAuth server...
The problem was that my server operates entirely in JSON, and doesn't display any kind of page (being pretty raw).
Thanks for the hints though, I'll try to work it out, somehow.

I've been looking into that as well, but I still can't see where the authorizationURL is used

I've been looking at the code of the nodebb-plugin-sso-oauth, attempting to implement it, and wondering...

Where does it actually send the password to the OAuth server?

Now it appears to be solved

As of today, using NodeBB v0.7.2, the bug is still present, and the circumstances seem to match the ones described by other users here.

I'm having the same problem, using NodeBB 0.6.1(master branch, cloned from GitHub) and MongoDB 2.6.7 on Mac OSX 10.10
