Hi,
It might be related to upgrade. You should re-organize the modules.
Modules are displayed on pages based on itemID, and itemID are assigned to pages based on Menu Item.
Showing modules on pages, or hiding them, have absolutely nothing to do with CleanMart. It is 100% related to Joomla (not even Virtuemart). We don't provide free support or step-by-step instructions if the inquiry is not related to our templates.
You may try this extension:
extensions.joomla.org/extension/metamod to have full control on what module to show on what page(s). But this module is little complicated to use. If you are newbie to Joomla, i wouldn't suggest you to use it.
Regards.
