WARNING: /home/vagrant/www/piwik/plugins/SitesManager/SitesManager.php(120): Notice - Undefined index: exclude_unknown_urls - Piwik 2.15.0-b3 - Please report this message in the Piwik forums: http://forum.piwik.org (please do a search first as it might have been reported already)
Do you see the exclude_unknown_urls column in the
site table? Should have been added as part of an update.
Nope, I presume the update wasn't inserted because of some weird switching between branches or so. Closing it for now and executing update manually
FYI: I just had a similar problem that an update was again not executed and noticed it is probably because of this commit: https://github.com/piwik/piwik/commit/90372750b039ce0b2150d4d6b1279fecbb245465 I might create an issue about this
