So I just launched my forum (http://ovcball.net/talk) and keep getting an error every time I attempt to set up JSconnect (I'm using Vanilla 2.1) I took a screen shot of the error information
did you try
ALTER TABLE GDN_UserAuthenticationProvider ADD IsDefault BOOLEAN NOT NULL DEFAULT FALSE ;
it's a bit unfortunate this isn't cleaned up yet.
so the same question isn't asked over and over and over.
but then again it never hurts to read the existing comments in any plugin before attempting to use it.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
Thanks for the link...sorry I didn't find it myself
The Problem is that the current version of this plugin is for the unreleased 2.2 version of vanilla.
