Why are some of my JReviews pages showing homepage modules
From JReviews Documentation
When certain page doesn't have an ItemID in url, Joomla will show on that page only those modules that are set to display on all pages.
But some Joomla templates (mostly RocketTheme templates) have a feature to instead show all homepage modules on pages without ItemID and that feature is enabled by default.
To disable it in RocketTheme templates, go to template parameters, click on Advanced and at the bottom you will find this setting:
You can turn it off or change the menu whose modules you want to show on pages without an ItemID.
If you have this issue for listing detail pages also, it means they don't have any ItemID which is not good. To fix that, you should create the Required Joomla Menu Items.
