Problem/Bug My first server error, HELP!

Hello, when I start my server everything works fine, and I can reload the server without any error nodes.

But when I reload my server when I've joined it, I get a weird error code.

Error Code Here!

The plugin bPermissions has an invalid config in which the default values for its config are null (don't exist). In Java this is very bad, in certain situations. It is a code error, however you can try to locate the default config file and manually add it. You can also check for a bPermissions update or use an alternative plugin.

EDIT: Your server also appears to be having TPS lag. If you don't know what this is or that it's an issue, you can allocate more RAM to your server. Decreasing plugin amount/world amount may also help.

 

@Superior_Slime Yeah, i moved a server to an older computer with 2ram, i might increase it.

Okey, thanks I'll look into the bPermissions

**EDIT**

Wait, is there a way to incease the RAM on a server? So i can get maximum out of my computer?
If u know what I mean? (Worst English EU)
