Trying to manually update Piwik from 0.5.4, I first got the message : "Database Upgrade Required
Your Piwik database is out-of-date, and must be upgraded before you can continue.
Piwik database will be upgraded from version 0.5.4 to the new version 0.5.5."
I clicked the “Upgrade Piwik” button, and after a few minutes got the message “Piwik has been successfully updated!”
But when I click the button “Continue to Piwik” The same first message “Database upgrade required” shows again ! So I re-upgraded again and again , successfully again, But still get the message “Database upgrade required” and cannot access my statistics.
My database seems to be well updated, the table piwik_option / version core shows 0.5.5.
Is there a solution ?
