If you're having troubles with getting the plugin to work follow the following steps:

Is the plugin loaded?

Does the plugin show up in /pl and is it green? If it’s not there, you might not have installed the plugin correctly or haven’t restarted the server yet.

Is the config correct?

Make sure that your config is correct, and that the enabled setting under main is set to true

Are you using the keepinventory gamerule?

BetterKeepInventory will only work if KeepInventory is enabled. Multi-world plugins like Multiverse tend to make game-rules act per world, So if the plugin works in the overworld but not the nether, Make sure it's set there too!

BTW: If you are using essentials, the essentials.keepinv permission works as well

Do you have the bypass permissions?

If you have nodes like *.* or betterkeepinventory.* you give yourself the bypass nodes, so the plugin will ignore you! Either don't give yourself *.* or negate the betterkeepinventory nodes.
