Hello Jay the change I noted should be correct you can not use a url in that path therefore you need to use a server path and the one I noted should indeed be correct.
$rppath is a server path. The other one that was there before was a url. If you have the same error as before then you have not changed it in the right file etc. Since we dont support or write a block for vbadvanced I can only tell you how to change it in the block we write for the forum page.
