Hi,
I tired it many hours without any success.
But finally it works for me.
My forum is 3.7.3 and vBa 3.0.1
check out
http://forum.xbox-offensive.eu
what I did:
first:
Do not change the line in step 1
var vburl = '';
leave it as it is!
second:
now do the second step, there has nothing changed
and third and last step:
add a new module in your admin panel as you see in post number #212
now it shows me my content without any problems
