Magento [SOLVED]Can not login to admin panel and website footer error 'Access to undeclared static property'

Fatal error: Access to undeclared static property: Mage::$_isDeveloperMode in app/Mage.php on line 881

Go to Mage.php line number 881 find the function.

public static function getIsDeveloperMode()
{
    return self::$_isDeveloperMode;
}

This method simply returns a static property $_isDeveloperMode of the class app\Mage.php. You can find that the definition of that static property
 in that file itself in line 117 (magento 1.9.1) like this.

Add below code of the class app\Mage.php "static private $_isDeveloperMode = false;"

Find: static private $_isDownloader = false;

    /**
     * Is developer mode flag
     *
     * @var bool
     */
ADD: static private $_isDeveloperMode = false;

I tried the solution and it work fine.

Joomla : 500 - PHP regular expression limit reached (pcre.backtrack_limit)

Hello,

I also got this error 500 "PHP regular expression limit reached (pcre.backtrack_limit)" on my website Top iPhone Apps created in Joomla 1.7.3

This occurred when I created so many menu items. After searching forums, I was able to fix it.
How? Here is the solution:

This is some kind of php restriction and you will need to override this php restriction by modifying index.php on your root.

Add following two lines in index.php and you don't need to modify any other file:

ini_set('pcre.backtrack_limit',1000000);
ini_set('pcre.recursion_limit',1000000);

Once it is modified, clear your cache and reopen your website. Its working fine.
