Version: OK(PHP 5.2.3 detected)
Checking PHP extensions
The following modules/extensions are required to run RoundCube:

PCRE: OK
Session: OK
DOM XML: OK

The next couple of extensions are optional but recommended to get the best performance:

FileInfo: NOT AVAILABLE(See http://www.php.net/manual/en/ref.fileinfo.php)
Libiconv: OK
Multibyte: OK
OpenSSL: OK
Mcrypt: OK
GD: OK

Checking available databases
Check which of the supported extensions are installed. At least one of them is required.

MySQL: OK
MySQLi: OK
PostgreSQL: OK
SQLite (v2): OK

Check for required 3rd party libs
This also checks if the include path is set correctly.

PEAR: OK
DB: NOT AVAILABLE(Use MDB2 instead)
MDB2: OK
Net_SMTP: OK
Mail_mime: OK
iilConnection: OK

Checking php.ini/.htaccess settings
file_uploads: OK
session.auto_start: OK
magic_quotes_gpc: NOT OK(is '1', should be '0')
magic_quotes_sybase: OK

Sorry but your webserver does not meet the requirements for RoundCube!
Please install the missing modules or fix the php.ini settings according to the above check results.
Hint: only checks showing NOT OK need to be fixed.
