After update to 3.9.1,. the icons for pages visited in visits log/visits in real time have no longer colors and they became grey. Is this a new feature, is this a bug, or is there a problem on setting of our server?
That’s a feature, see Visits in Real-Time actions icons size/color style · Issue #14241 · matomo-org/matomo · GitHub for a discussion.
Too bad. Is there a safe way to revert to an older version? I didn’t backup the database before upgrade.
