Homepage blank white, but posts ok.

steelotter.com

Running WP 3.2.1, upgraded and reinstalled several times to be sure.
As per advice on: http://www.velvetblues.com/web-development-blog/my-wordpress-blog-is-blank/

Have also just reinstalled WP manually using FTP with no change. Followed instructions on: http://codex.wordpress.org/Updating_WordPress#Manual_Update

Using ipage to host.

Theme is canvas 4.4.1
Framework is 4.2.0
All widgets deactivated.

Posts show ok. White screen o’ death for the homepage.

Homepage works with:
Twenty Ten 1.1 and proSlate 1.31

Doesn’t work with:
Canvas
Twenty Eleven 1.2

Possible permissions or database update issue? Not sure how to do either of those things. Any help appreciated!
