So I upgrade to WP 3.0.1 using Atahualpa and cannot edit pages. Page, edit, left menu but no text, no nothing. Bad. Have to hold off upgrading all the other blogs. Upgrade Atahualpa to 3.5.3. No good.
After weeks of search, found this post which sez PHP4 does not cut it.
What does 1&1 supply by default?
(uiserver):xxxxxx:~/xxxxxx> php --version
PHP 4.4.9 (cgi) (built: Aug 12 2008 13:28:34)

Update .htaccess. Add:
AddType x-mapp-php5 .php
Works nice. Thank you very much.
