Hi,
The server was running PHP version 5.5.x, upgraded to 5.6.29, the site runs with Yii1.1 and MySQL. All went fine, the task is completed, but the bounce rate has been increased in the next day dramatically way, would be that related to the PHP version which I don’t think that personal, or change to the visitor behaviour?
Note that the site was down after the upgrade for 3 days due to DNS issue.
What you think the issue, and how to solve it?
