Issues after zencart upgrade..

We recently upgraded Zen cart on our website and are facing the following issues now: 1) The first one is easy to check- if you click into any product, the name and model ID disappear. 2) the second one happened when I add a new colour, it just would not let me. Then I tried to edit an existing colour, it does nto save the change either 3) The third problem is truely bizzare- whenever I updated the image for New! 2 in 1 Tie Back Top black, the image of New! Dotty Nursing Top Navy will change as [login to view URL] two images seem to be linked somehbow Need some one to fix these 3 issues.
