V1.3.9H And Upgrading to V 1.5.4 Get Blank Screen when clicking on New Products

V1.3.9H And Upgrading to V 1.5.4 Get Blank Screen when clicking on New Products, and i notice in the url it gives a ZEN ID and then a long number. (Testing on my dev site)

When this happens it give me a blank white screen.

Then I use the back button and click on NEW PRODUCTS again, and it works just fine.

Any suggestions? i know on my old site, that when it said the www. whatever it was and then at the end it would say ZENID= then the long string of numbers just the same, but NEVER had a blank screen
