This is less a bug than weird behavior:

I'm porting a Blosxom blog to MT. The MT code is completely stock except I've installed and am happily using the simplecomments plugin. Everything was working fine. I was mucking around with the templates. I rebuilt, mucked around some more, rebuilt, etc. At some point, I started getting warnings when I rebuild. The rebuild works fine, but I'd like the warnings to go away. Any help would be appreciated.

Thanks.

I almost forgot. I believe the warnings appeared when I tried to link my main index to a template using the option on the Edit Template page. The file I tried to link to did not exist. When I rebuilt, it created the file but gave me warnings, so I deleted the file and removed the filename from the Edit Template page.

But now every rebuild is accompanied by the messages listed above.

After some more testing, I've discovered the warnings only appear when rebuilding the indexes, as opposed to the various archives.
