@knelus are you using 2.7.0? can you reproduce this error on the demo?

Hi Matt,

On the demo the visitors log works perfect.
But not on my server. I work with php 5.3 so I asked my hosting provider to do some research about upgrading my php version.

Someone in the german forum has the same issue after upgrading from 2.7 to 2.8.
@knelus are you still having that issue?

Hi there,
If you still experience such a bug in 2.8.3 then please open a new issue at: Issues · matomo-org/piwik · GitHub

hmm, i thought I turned on email replies… o wel…
But yes, still having the problem. I will have a look on the german forum and if that doesn’t fix it i will report the bug on github.

Thnx for replying guys.
