What version of PHP are you running ? I had the same issue when first installing Elgg 1.10 and it was due to my php version.

I don't know how I can see my PHP version

Ok, I'm using PHP Version 5.3.10-1ubuntu3.11

Yeah you would php 5.5, 1.10 doesn't play nice with old php versions

The error log says that:

[Sat Feb 28 01:54:25 2015] [warn] [client 84.127.22.41] mod_fcgid: stderr: PHP Parse error:  syntax error, unexpected '[' in /var/www/vhosts/licaweb.com/presupuestocero/engine/classes/Elgg/Di/ServiceProvider.php on line 194

Elgg requirements:

• MySQL 5+
• PHP 5.4+ with the following extensions:
  • GD (for graphics processing)
  • Multibyte String support (for i18n)
  • Proper configuration and ability to send email through an MTA
• Web server with support for URL rewriting

My server is OK for that requirements. I don't undestand why the Elgg installer is not working and I only can see a white page

Requirements haven't been updated yet, I've had your problem before and updating to php 5.5 fixed it.

Agreed - update your php to the latest and report back. It fixed my install

Your server is not meeting those requirements

The listed requirement is 5.4+ (which as mentioned may have been bumped to 5.5 for Elgg 1.10)

You previously said your server was running

PHP Version 5.3.10-1ubuntu3.11

Upgrade PHP and report back please!
