Hello HexOptimal,
Thanks for your answer.
I completely removed the plugin/config/data files. Load the plugin agin. (Spawn Modular Car plugin is installed too)
As I con't find the buton police vehicles into Perms Manager, I enter into the F1 console I type "PoliceVehicles.use Tof" folowed by "PoliceVehicles.unlimited Tof" (without the " ") .
Then I try to spawn a car with the chat command "/policecar". The answer I get is "You do not have permission to use that command".
As it seems to be a permission issue, I am not sure I give it correctly.
I hope it give a better view of my issue.
Br,
Tof
