We are using Piwik 2.14.0 to track multiple sites. The biggest site gets about 8,000 hits a day. The piwik_log_visit table has about 11 million rows in it.
When I attempt to create a new segment, everything works fine until I click the Save and Apply button. After clicking the button, it displays the ‘Loading data’ message but, never completes.
I changed logging to DEBUG in the config.ini.php but, nothing shows up as a problem. I don’t see anything related to UI activity in the Apache error log, the access log, or the mysqld log.
Does anyone have any suggestions on troubleshooting this, aside from upgrading to 2.16.0?
