I changed a theme for my sister's blog and I noticed all the Comments for her 'Guestbook' page have vanished. This was one of the Pages for the blog itself, not an individual article:
In fact, all the comments for the blog articles are intact. Only the Guestbook Page has its comments missing. And I noticed that if I switch to any other themes, the comments remain missing; but when I go back to her original theme, the comments return.
Any help is appreciated, thanks.
