On other Blogger managed comment sections on other sites the comment disappears (for moderation), but not the whole comment section. Make sure you are not interfering with the Gadget.

Edit your post (any one of them) - on your right, click on 'Options' - What does it say under 'Reader Comments'?
Also, make sure the comment box under 'Dashboard - Layout - Blog Posts - Edit' is checked...
Another thing to make sure is your settings. Go to Dashboard - Settings - Posts and Comments - Comment location - Embedded.
If you think all these settings are right, and you still aren't seeing your comment link/form, try resetting your template. First, make a backup by going to Dashboard - Template - Backup/restore - Download Full Template. Next, go to Dashboard - Template - Edit HTML - Proceed - Revert Widget Templates to Default.
A second answer is offered for Disqus users.
It's difficult to read the source (Firefox or Chrome) due to the packing function see: eval(function(p,a,c,k,e,r) but you can see that the comments section is visible in the source of the second link above.
When I view the source I can see: " 'disableGComments': true " - search for that text in the page source view. Please note that comments from Google are no longer supported. Check that your (unnamed) 3rd party template has been updated; perhaps the 3rd party script is interacting with the website and its seperate commenting mechanism.
You can manage your comments and approve them if necessary.
