I had issues with the statistics generating php errors which are currently solved. However, I still have issues with referal stats and search string status under php 7.1(+). Sometimes there's a line showing one record of statistics which is empty the next day. It does not reply with a consistent answer, most of the time the statistics are empty. I'm sure that at least something should be presented as the site is running for over a year now. Anybody facing similar issues? Is this a bug?
