I tried to restart economics & Reward plugins
delete old VL files (also data) and the load the new one
reset the server
I have enough money to buy any item (in-game)

I tried everything but the Vehicle License plugin is not taking the money in game, also I check the other plugins (economics) all work fine.
I get this message "you dont have enough money to buy ___"

any help?

Please send your config

This is the error that my players, admins, and myself have been getting from the plugin after Forced Wipe and updating the plugin. The weird part is that the plugin was working up until a certain point.

This started about a few hours ago, I am using Server Rewards RP as the purchaings currency for the items. I have attached my config file, incase anyone wants to take a look, but its not making any sense.

Again, upon initially updating the plugin I was able to make purchases. I did infact change all of the permissions for applicable groups to the new permissions, so that should not be an issue.
