Thanks Kelvyn
Changing the list setting to 25 fixed the problem, but it begs the question, why have VMsettings that get corrupted if they are not the same as Joomlas 25.
I have 6 categories with 9 products in each category. I was trying to set the page limit to 9, so that each category shows on its own page. This conflicts with Joomlas 25.... why bother have list length settings in VM3
Thanx for your help anyway
