Pur3x

Thanks for the advice but im still having this issue, i deleted the kits_data,the lang file and the config file and reloaded the plugin, and i'm still having those errors. Any other ideas ?

Merged post

I found out the issue, some kits weren't redeeming forr some reason so i just edited the kit and re-added the items to the kit and saved it again.

If there is no problem can you mark the issue "solved" , saves people reading already corrected problems
