I had cart version 1.3.8a. In my hosting control panel there was an option to upgrade. I clicked on it and it informed me that it could only upgrade me to 1.3.9e and then I would need to run the upgrade process again to get to the latest (1.3.9h). So I hit upgrade and off it went. All appeared good until it finished and gave me a "Complete Upgrade" link which tried to launch zc_install. Only problem is zc_install/index.php never loaded...blank white page. I found 1.3.9e at sourceforge, downloaded it and uploaded that zc_install folder. Tried to go to zc_install manually, but still blank white page. I can login into the store's admin panel just fine and go to the storefront just fine. The store front and admin server info both show I need to upgrade the database. From reading here I have to do that in zc_install, but that page is blank. Help?
