I installed the latest version since the wipe 01/06. Now when you type the buy command there is no list of vehicles or commands you can type. Players no longer have access to buy, recall, or anything. As an admin it says i do not have permission or the vehicle name doesnt exist. but everything has been filled out correctly, and permissions are all correct in oxide.

Did you update the latest version of the plugin? If not, the plugin is not loaded and would explain your issues.
