1. Do you have cookies setup right? cookies the same in both?
cookie path /
cookie prefix bb
cookie domain .yoursite.com
I use facebook connect with vb4 forum and all seems right. I would assume the facebook connect thing also makes any proper vb
cookies which is of course what we read to know who is logged in.
If your cookie settings are not exact between both apps then you will not be carried over being logged in
2. two things to consider I do not see a brador cat.
Now any category that is a top level category which has subcats you would set to contains thumbs to NO. that is what tells the program to show that collapsible bar.
You do not set a category as collapsible when it contains images.
In the end it is always how you have things setup.
