Info: logs

Please post your full latest log file.

Background Info: One of the most helpful tools to identifying the source of a problem is your server logs file! Logs contain all sorts of important information like server and plugin versions, any error messages, and a lot more important information (More Info).

How To: Your log can be found in the logs folder within your server folder. The most recent log is a text file labeled latest.log. To get help using these logs, please open that file in a text editor and copy all of the text, then open https://paste.denizenscript.com/New/Log and paste the text into the box on the page. Then click "Submit" and copy the URL and paste that back into this channel.

Please do not upload the file to Discord or to other pastebin services, use the log pastebin linked above.
