I try to find out all the time why my server always lists who a player Joint these errors on
Unfortunately, we do not have your ServerLog (or the section with the error message) to give a more detailed info.
Which mistake?
You probably forgot to add it.
How can I upload this?

Ai ai ai, that's what… If I read correctly, the half to three-quarter log consists of consecutive error messages. Relatively at the beginning one can already read that he has problems reading the plugin correctly. I can't tell you from here whether that is due to a wrong attitude. Or if the error is caused by the programmer.
But maybe someone else here can interpret the error messages better than me ^^
Which plugin?
: D and thanks
Could you copy the entire log file (the content) and put it on https://hastebin.com/...stebin.com and then share the link?
There's no sign limit and everything is nicely formatted.
Please send the error with a paste page like Pastebin or https://mclo.gs/
