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
- 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!
- Dashboard graph is not working. It shows broken images regardless of any selection.
- Reports that require to input a date range are not working. It keep showing ‘No Records’ even if i refresh the statistics
- Even to the extend of doing fresh install of Magento (i tried 1.8.1) also gives the same errors above
