Tracebacks and Comments broken in my WordPress

I am using WordPress ver2.7.
I have enabled Tracebacks/Pingbacks on my posts by checking the box:
Allow Tracebacks and Pingbacks on this post.
I have also enabled Comments on my posts by checking the box:
Allow Comments on this post.
I have also enabled the global settings under Discussion to allow tracebacks, pingbacks and comments.
I have 4 simple plugins that do not interfere with the posts. They are:
Add to Any: Share button
Add to Any: Subscribe button
Adsense Manager
Page Links To

I am using Thematic theme

My website is: https://www.prolificliving.com/blog
______
Everytime I publish a post, I get this:
Both comments and trackbacks are currently closed.

I update the post by varying the settings above, to no avail. The changes in settings don’t change anything.

It is driving me crazy. What am I missing please?

Please help me.
Thank you,
Farnoosh
