Do you know which version of magento you are running?
If it hasn't been removed by your frontend developer, then you can find it in footer in both frontend and admin pages. If it has been removed then you can check it in app/Mage.php. These two functions will return current magento version.
/**
* Gets the current Magento version string
* @link http: //www.magentocommerce.com/blog/new-community-edition-release-process/
*
* @return string
*/
public static function getVersion()
{
$i = self::getVersionInfo();
return trim("{$i['major']}.{$i['minor']}.{$i['revision']}" . ($i['patch'] != '' ? ".{$i['patch']}" : "")
. "-{$i['stability']}{$i['number']}", '.-');
}
/**
* Gets the detailed Magento version information
* @link http: //www.magentocommerce.com/blog/new-community-edition-release-process/
*
* @return array
*/
public static function getVersionInfo()
{
return array(
'major' => '1',
'minor' => '7',
'revision' => '0',
'patch' => '2',
'stability' => '',
'number' => '',
);
}
From above function you know it's version is: 1.7.0.2
You can create a file on your magento installation root and call this function by simply:
include_once 'app/Mage.php';
umask(0);
Mage::app("default");
echo Mage::getVersion();
