Blank page after Create Account

[Doodlebuckets]

Accounts are created, but user is sent to a blank page. Actually, it's the same page, http://www.doodlebuckets.com/zen/ind...create_account but the page goes blank. Any help on this? Do I need to look at the tpl_create_account.php or the tpl_create_account_default.php file? When I delete these from my overrides, it still happens. When I replace the files in my overrides with the 1.3.8 files, it still happens. This is a fresh 1.3.8a install with which I have imported my database from my 1.3.7 store.

1.3.7 store is http://www.doodlebuckets.com/store/
1.3.8a store is http://www.doodlebuckets.com/zen/

After I build the 1.3.8a store, it will then take the place of my 1.3.7 store. Any help is appreciated!

Same thing happens with the login page too! It goes to http://www.doodlebuckets.com/zen/ind...create_account but it's blank.
