Please take a backup before installing this version, that way if something goes wrong you can restore to a working point!!!
Should be good to go with XF 2.2 Only thing you need to do is turn off the polls in the node(s) under the setting "Allowed thread types" for the music forums.
There is no need to repeat anything. Before I wrote here, I looked at the api key. (5d656564694f534d656564)
But it's not working. I don't want to hold it up anymore.
What is that you want the widget to do? I adjusted the standard widgets to show album covers with name of artist and name of album on my own site have a look and see if this is what you would like the widget to do and I'll help you out with it.
No! I adapted the standard Xenforo widget to show the music albums. I had to manually edit the template for the topics, which basically meant I had to add certain things and move a few things around and add to extra CSS to make it work as you see it on my site. I would send this to you via email, but for some reason or other my email addresses are not liked by Google mail. BTW. I manually approved your account on my site because the email it sent out to you for confirmation bounced lol.
