Magento

I have installed magento succesfully, but can\\\’t get to it, what went wrong? Please advise, thanks

Exception printing is disabled by default for security reasons.

Error log record number: 827411200148

First check error it will be in [root directory of your magento]/var/report/827411200148

Possible solutions :

Give app/etc , var , and media folder the file permissions of 777

[root directory]/lib/Zend/Cache/Backend/File.php
look for code :
protected $_options = array(
\’cache_dir\’ => \’null\’,
and change it to
protected $_options = array(
\’cache_dir\’ => \’tmp/\’
and save it
