After I update from 1.9.0 to 1.9.1, no visits are being recorded.

Logs show

See also bug here: http://dev.piwik.org/trac/ticket/3477

How to resolve it:
remove “GeoIP” from [PluginsInstalled] and [Plugins_Tracker] sections in config.ini.php

Already not present here.

It’s not serious have blocking bug at each version of piwik!!!

Do unit test before push an update please.
