Installation of Matomo 3.4 in my local LAMP environment works fine.
But installation of the same zip-file in a shared hosting environment failes.
The first step (systemCheck) ends up in HTTP 503 error.
With developement mode enabled I was able to complete installation.
After some further investigations, the error seems to happen in Filesystem::globr() during FileIntegrityCheck.
I tried php 5.6.x and php 7.0.23.
Can anybody help?
