For a few months after i have upgraded to 1.6.x and to current 1.8.x, i have been facing the following issues/behavior in backend admin

1. Searching by fields in every view(Sales, Order, Catalog, etc) are not possible. All searches will return all result back. It seemed as if filter is not working!
2.  Dashboard graph is not working. It shows broken images regardless of any selection.
3. Reports that require to input a date range are not working. It keep showing ‘No Records’ even if i refresh the statistics
4. Even to the extend of doing fresh install of Magento (i tried 1.8.1) also gives the same errors above

I just recently upgrade one of my magento ecommerce website from 1.7.x to 1.8.1 and one of my customer feedback that he encounter a javascript undefined error upon checkout.

After some comparison with the base folder of magento 1.8.1, i figured out that you need to amend the following page.
