The solution to this is just installing the 1.1 version which can be found here. I'm not sure if this happens to everyone or only when you install the patch by overwriting patch files through ftp that is how I did it.
You should to go to app/core/Mage/Adminhtml/Helper/Sales.php then look for some code like this $links = ; and change to $links = array(); for me it is at line 124. Or you can search inside Sales.php file using ctrl+f command , and try to search for  then change to array(). Hope it helps you. Thanks!!
var/report. But where can I see such non-critical error information?
var/logfor Magento logs. To get your server error logs, you can do it via cPanel or an other server admin web access. If you have full access to your server via SSH you can find them in the
var/log/system.log. The problem is the file weights 20GB and it would take a lot of time to download it.
