Jooma 2.5 Logged out of Admin Site Due to Force Admin Site SSL

* Jommla 2.5.18

* Accidentally set Administration > Global Configuration > Server > Server Settings > Force SSL to Administrator Only without setting up proper SSL certificate

* Now you cannot access the Admin site. I got the output when I saved configuration:

<META HTTP-EQUIV="Refresh" CONTENT="0;URL=http://my.com/administrator/index.php?option=com_config"><h1><a href=http://my.com/administrator/index.php?option=com_config>VIEW TEMPORARY SITE</a></h1>

* Login cPanel
* Locate Configuration.php file
* Set file permission to allow write access

* Open Configuration.php file in edit mode
* Set $force_ssl to 0

public $force_ssl = '0';

* Save file
* Set file permission back to disallow write access

* Check that you can open Admin site without using SSL now
