I've installed TY tracker 3.1.1 onto zc1.3.9 with EO 3.0.3. Everything appears to be working on the admin side (I've not tested the emails). Although I have checked on the Catalog side and I'm getting a blank page when i click on the order history ...index.php?main_page=account_history_info&order_id=... I've gone through many times and tried to find the file that may be conflicting this but I'm unable to see where the error is being generated. I've checked both the server error log and the cache log and do not see any errors being generated from this issue. Yes the tracker module is also set to True.

Thank you.
