Hi I have 2 issues that my host have advised that it may be bugs in zen cart so I need help.

1st issue
Orders that come in appear in Orders for a while, after I update the orders to processing, a while later it disappears from my Orders page. If I search for the orders, it's there but not showing up. And when i go to phpadmin to check, the order status have turned to 0 and i have to manually change it to 1, 2 or 3. I've missed shipping a few orders because it disappears and I didnt realise i had an order. How do I fix this?

2nd issue
Whenever i add a product or modify a product, after i click the Update button after the Preview, instead of updating the product it goes to the main Admin page. At times I have to update a product at least 4 times before it gets updated.

Thank you in advance for all the help!
