Hey everyone

This is the link of my website .
paola.vedmal.com
I want to update it to latest version.Currently i am using 1.8.1.0 as it  shows in admin footer.
I want my magento website to be update in Latest version that is  ver 1.9.2.1 .
I have  found a solution via  Magento Connect Manager .
According to  solution the Mage_All_Latest option is need to be updated ,but when i click on Check for updates its shows that we are already using Latest version (1.9.2.1) ,no update available for Mage_All_Latest.
But the issue is that it is still showing older version in Footer in admin panel.
Kindly help me out.

Thanks in advance.

Hello,

It seems like your store is not fully upgraded. Please check for upgrades in magento Connect Manager and select all options which is available for update and submit.

Your app/Mage.php is still not updated to new and due to that its showing old version.

Thanks
