I suspect there is a simple solution, as i am having the same problem on a fresh install of Vehicle Manager and Real Estate Manager...
I cant view the vehicles. For example, when i click on a vehicle displayed in the slideshow or vehicle displayed in VehicleManager New Vehicle Extended free module, i am taken to the category page, not the page of the respective vehicle. Also, when i click on a category, it seems to simply refresh the page, not list the entries in the category.
What am i missing?
