After updating from 1.4.10 to 1.4.12, the index page is no longer displayed after login. It remains the login page.

Best contact the author of the theme. Maybe he can help.

Did you contact the theme's author? If it works in the official themes for you it is a theme issue and then it's his task to fix that. I quickly tested it and it seems to work.

And as always the usual question: What errors in the error log?
