Installation stucked over and over.

Hi everyone, 

I installed Moodle 2.7+ on my localhost and everything worked fine.

Now, I'm trying to install Moodle 2.7.1 on my webserver and I got stuck at the "Installation" page (after clicking Continue when the Moodle evaluates the php compatibility with my server). 

The browser freezes at a certain point. I've waited more than 30 minutes and nothing changed. In a desperate move, I clicked at "Continue" again and the browser returned me a bunch of errors. 

I tried it at least 5 times and I got the same results... Tried to install the 2.6.1 but didn't get any luckier. 

Could you guys help me, please?
