Blank page after admin log in

For some reason my password quit working. I used the instructions posted here - http://www.zen-cart.com/content.php?44-how-do-i-change-or-reset-my-admin-password-%28i-lost-it%29

Now I log in with out an error message but get a blank screen. https://www.my_domain.com/zc_admin/login.php?zenAdminID=3t9gbtkoprrg5i2pbh8vit55c3

Looks like the website is still working for customers to buy. Has anyone else seen this? Thank you

This article has information on troubleshooting blank pages: I am getting a blank page. Please post the contents of any "myDebug-adm-xxxxxxx.log" files (use code blocks -the # button). Also please answer the other questions found in the "posting tips" (including how Zen Cart was installed / upgraded and the version of PHP running on the website). This information will help us help you :smile:

Also as part of posting the contents of the log, be sure to obscure your secret admin directory name. Ie, change it to admin instead of the secret admin directory you have chosen.
