Plugin Help! Simple Region Market, and uSkyblock!

hello! I need help D: So recently i started a skyblock server and I set up Simple region market, with little stalls where players can rent them out and make shops. But they can't add more than 24 hours. They can click the sign once to rent, then can't expand their time. Idk what to do. With uSkyblock When a player restarts/creates/joins another island, their inventories reset. I know its possible to make it not do that because I once got on a server where your inventory saved even after switching between islands. Thanks!

 

modify your plugin config.. i dont know about UsSkyblock, but if it possible, you can find the problem in your plugin config file

 

Multiverse inventories will fix your inventory problem, but as for your Simple region market problem, that is one of the few plugins I have no experience with.
