Not blocking category?

Hi – I have IQ Block Country implemented on my site and am trying to set it up to block specific categories from certain countries. I’ve selected the category and selected not to block the front page (from categories tab), but still have access to everything. WHen I block the front page from the categories tab, I still have access to everything. When I choose to block the front page (from the front end options) I have access to none of the site.
Where am I going wrong? I’ve completely disabled my sucuri cache and not sure what to try now – as I figured it was interfering.
