Installation: Internal Server Error

[tazmandev]

First go to gsconfig.php (rename temp.gsconfig.php to gsconfig.php if there is none ) and
# Turn on debug mode
#define('GSDEBUG', TRUE);

remove the # in front of define('GSDEBUG', TRUE); so it becomes:

define('GSDEBUG', TRUE);

Now try again and you will see the exact error.

I had a problem din DOM/XML not being installed on my server, (allthought simplexml was installed) and after a:

yum install php-xml

and restart apache, everything worked fine.
