Moved from 1.2.2 to 1.5 – problems encountered

Hoping to switch to Mallow theme, I upgraded from 1.2.2 to the nightly build of Feb 06. Following are some of the errors I’m getting.

To upgrade, I backedup and deleted the entire WP 1.2.2 install, except for config.php. Uploaded the 1.5 build, then uploaded Mallow theme.

Any suggestions mucho appreciated, steve. Errors follow – I’ve inserted the flagged code lines if that helps:
