Problem with cg-amazon / blank page

I followed the WP 2.0 upgrade instructions as follows:
— backed everything up
— deactivated all plugins
— deleted old WP stuff
— uploaded WP 2.0
— ran upgrade.php
— went into wp-admin and chose the default presentation

I browsed my site, and everything looked hunky-dory.

I downloaded CG-Powerpack from the version 1.5.3.1 link on chait.net. I deleted all of my old CG plugin files and installed the new files.

I then activated the cg-amazon plugin. Browsing to the site now produces a blank page. I can see/do anything on the admin pages, but I can’t see anything on the main site.

Deactivating cg-amazon brings everything back.

There is nothing in the default theme that is using cg-amazon. I can activate cg-inline with no problems, so this isn’t a problem with the whole Chait powerpack.

When I bring up the manage plugins page, it shows cg-amazon as being version 1.5.2 instead of 1.5.3.1. I don’t know if this is significant or not. The file I downloaded did have the name CG1531.zip.

I checked all of the cg powerpack php files for blank lines at the end. There were a few. I delete the blank lines. It still produces a blank page.

I’ve searched the support forums and can’t find anything on this.

I’ve fallen back to WP 1.5 until I can get this figured out. I use cg-amazon quite a bit, so the is a real showstopper.

Thanks in advance for any help.
