I'm have 2 problems:
1. The page number is not showing up at the end of frontend products page though I have more product on next page. It was there with all of sudden I have noticed that it's disappeared.
2. At the backend product page Stock Quantity is shown twice. One of them is greyed out, so when ever I make some changes in product and save it, it takes value 0 from greyed out quantity and my stock becomes 0.
