Well, that wasn’t too bad. I have made a couple of minor fixes to the AZIndex’s administration interface while should allow you to edit and modify your AZIndex settings as before (prior to installing WordPress 2.7). The changes are backwards compatible with older versions of WordPress (2.5.x and 2.6.x) so even if you haven’t moved up to WordPress 2.7 yet, you can safely install the new version (not that it will do anything for you!).
I will now work through the backlog of comments to see if there is anything else that needs attention. Thanks for your patience — oh, and a belated Happy New Year to everybody.
