My 1.16.5 Minecraft Server won't save player data but saves world data

I have a minecraft server and just recently installed plugins, everything worked fine. Then I decided to edit some prices for my shop. I reloaded a plugin, the server restarted and I noticed I was in a different spot. I tried putting an item in a chest, logged out, then had the item still in my inventory, but it was also in the chest. I broke a potato plant, had the potato in my inventory and didn’t replant, logged out, then logged in an the potato was not in my inventory and the potato plant was still broken. I’ve heard about write permissions, but I didn’t change anything that crazy. I literally just changed the price of some items.
