I installed this the other day in a store that had 1.5.7 and it was functioning, I upgraded the store to 1.5.7b and it functioned.

Today, on a fresh install of 1.5.7b, when I installed, it causes the client side "My Account" orders to dissappear.

Here is the corresponding log file. I have triple checked to make sure all files uploaded and the template folder named correctly. Please advise any help would be appreciated.
