Chromium 33.0.1750.152 (256984), the same on Firefox 28.0
openSUSE 13.1 & nginx/1.4.7 & PHP 5.5.10

Same here.

Tried almost every browser available on both Windows and OS X and I always end-up with that "it seems you tried to skip a step" message.

Hello @mruz13 and @ths-la, thanks for the report. Could you please send me an email at matt@piwik.org with your info? It would really help to have access to FTP to your server where we can reproduce and so we can fix the issues.

In your "System check" maybe you have any particular warning (such as NFS filesystem) ?

HINT: This happens a lot on OVH shared hosting, maybe related to NFS? http://forum.piwik.org/read.php?8,114216

A possible fix may be to move to Database sessions by default? http://forum.piwik.org/read.php?8,114216,page=1#msg-114449

Hey Matt,

Sent you an email this morning. Tell me if there's anything I can help you with to address this issue.

Just to give you a little more context, I'm on a Gandi hosting marketed as "Simple Hosting" which is basically a VPS.

In abe158d: Fixes #4990 Removing use of sessions during installation.
