[Mediawiki-l] Undisplayable Pages

[Shannon Appelcline]

I've gotten MediaWiki up and installed over the last couple of days, and
generally I've been impressed by a highly professional & good looking product.

However, I've already had a few different weird cases where pages just stopped
displaying.

In the first case I had to delete the page and recreate it before I could ever
view it again. Even totally emptying out the page didn't change it.

In the second case the original user couldn't display the page, non-logged in
users couldn't display the page, but I could. I added a space to the end of the
file, and the original user could view it again, but non-logged in users still
can't.

In each case, the page just doesn't show up. In Firefox it won't go to the page,
in IE it gives the familiar "The page cannot be displayed" page.

Here's what the debug shows on failure:

Here's what I see for the same page when I'm logged back in, and can
thus view it:

Any help is appreciated, because I feel like I'm sitting on a time bomb now,
with pages randomly becoming unviewable.

Thanks!
