When we try to login to admin it shows fatal error. So is there any solution for this problem?

Fatal error:

Access to undeclared static property: Mage::$_isDeveloperMode in /home/mominaslib/public_html/app/Mage.php on line 881

  • What version of Magento are you running? What is the fatal error? Can you copy/paste it here. – Matt Antley Dec 8 '17 at 14:34
  • It shows this ""Fatal error: Access to undeclared static property: Mage::$_isDeveloperMode in /home/mominaslib/public_html/app/Mage.php on line 881""" – Shahbaz Dec 8 '17 at 14:41
  • You modify your mage.php file? – Mohamed El Mrabet Dec 9 '17 at 8:15

I'd give https://magento.stackexchange.com/a/79637/41117 a read.

If you've made any changes to Mage.php then I suggest replacing it to the default version from your Magento 1 install and trying again.
