I do not see any emails from you to the photopost company I checked our helpdesk. I do not have details to any site your referring to as it has been along time since we discussed anything and I commented on things for you.
what version are you using?
I am using 5.21 Main Index - Reeftalk Reviews
Now I am using vb4 so things display a bit different but I checked my database and for example the online retailers section has 11 reviews through its children and I checked the database posts entry for the parent cat it shows 11 posts so its accurate.
Maybe try downloading the current code and reapplying the files and doing a rescan?
Your issue definately sounds like something I fixed in a prior version.
