Problem

When I go to project setings and try to add some categories and click "save", error http 500 is shown. ("Oops, an error occurred Please see your system administrator.")

Logs from Bitbucket:

Solution

Please check your database version. If you're using MySQL 5.7+ or MySQL 5.6.15 and earlier with Bitbucket 4.14, that's not supported. You can find further information on supported databases here.

Atlassian generally does not recommend MySQL for Bitbucket Server right now. We recommend PostgreSQL instead.
