Please help me to find out what might be the problem, for I'm close to despair right now. :(
I've installed WP about a month ago. Everything was okay at first, I uploaded a couple of themes and customized them a bit, but everything was working alright. :)
Then yesterday I suddenly found out that the comments are behaving weird. The comments form is not included into the posts or pages (it's not just me not seeing it - it is not in the source code of the page in the first place). The only exception is the only page where I have the only comment so far. This page does show the comment and the comments form, just the way it is supposed to do. On the pages and posts with no comments there is no comments form, although commenting is enabled.
I've checked and double-cheked for the relevant strings in the theme's code, they're all in place. I've tried all the themes a have (all five of them) to no avail, even with the themes I've never touched with customizations.
What can be the reason for this weird behaviour?
You can have a look here:
