help? i have a problem that i cant figure out, i have the rows set to "7" , and 7 appear but only 5 are uasable? am i doing something wrong or what?
thanks!

You likely have the permission backpacks.use.5 which overrides the default.

ok i revoked backpacks.use.large , and set the rows to 7 in the json file , and tried the backpacks.use.7 but its says that doesn't exist. sorry to be a bother im just trying to get it figured out this is my first month of having mods , so im relativly new to all the oxide and plugio commands. 
thanks again so much for the help, and great plugin brother! my players love it!

Can you tell me how exactly you tried to grant the permission please?

oxide.grant player backpacks.use.7 , i updated from an older one that had backpacks.use.large
