The internal redirect-after-edit is broken.
Make sure that your theme has a valid signature ImageAlias,
and not false.
$WikiTheme->addImageAlias('signature', "Signature.png");

This seems to be a special problem with apache2, but I got nearer in the 
last week.

Good idea! I had the same :) It's already in CVS.

DONE:
      *   More then 20 new external links (hardcoded)
          (have to update http://phpwiki.org/WikiSpam)
      *   content patterns by babycart (only php >= 4.3 for now)
          ENABLE_SPAMASSASSIN
          (have to update http://phpwiki.org/SpamAssassinIntegration)
TODO:
      *   IP BlackList
      *   domain blacklist
      *   url patterns

These need a working accesslog (best via sql) and 
WikiAccessRestrictions, which I deferred to 1.3.12
The hairy accesslog code is already done, but the interface and policies 
are missing.

See above.
