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 18.104.22.168. 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 in 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 calling cg-amazon. I can activate cg-inline with no problems, so this isn't a problem with the whole powerpack.
When I bring up the manage plugins page, it shows cg-amazon as being version 1.5.2 instead of 22.214.171.124. I don't know if this is significant or not.
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 fallen back to 1.5 until I can get this figured out. I use cg-amazon quite a bit, so the is a real showstopper.
I'm open to suggestions. Thanks in advance for any help.
