I have to crash the server to disable the server from hanging from it. To fix it all i have to do is disable the Teleport module

install PlayerAbilityLib

PlayerAbilityLib 1.2.0 and 1.2.1 does not fix this problem... unless there is a different one then curseforge can find.

This is not a complete error log. Please post a full crash report instead. Make sure to post it on a site like pastebin, hastebin or similar.

Caused by: com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: BLOB/TEXT column 'name' used in key specification without a key length

We've been getting more and more issues with MySQL, and we should look into whether we should make changes keep supporting it or drop it entirely.
