I include the screenshot, the original is here http://21.maidan.org.ua/2011/08/v-to...ij-v-ukrajini/

That subtitle basically says "3 commentsThe title of post goes here" - no space between the number of comments and post title

HTML code looks like this

	<h3 id="comments"></a><iframe src='http://www.facebook.com/plugins/comments.php?href=http://21.maidan.org.ua/2011/08/v-toronto-projshla-demonstratsiya-proty-politychnyh-represij-v-ukrajini/&permalink=1' scrolling='no' frameborder='0' style='border:none; overflow:hidden; width:130px; padding-left:-15px; height:12px;' allowTransparency='true'> 
			</iframe><a>3 коментаріВ Торонто пройшла демонстрація проти політичних репресій в Україні</h3>

Right now facebook comments are enabled, but I tested it without this plugin - nothing changes.

This is apparent error, however I don't know where to look in order to fix it. I didn't tweak WP core or Atahualpa at all.

Please give me direction where to edit that code.
Thank you
Viktor

Are you using a plugin to get the subTitles? Comments don't have subtitles

No, I don't. Sorry, I worded it wrong. It's post TITLE - added before the comments section.

I don't have any plugins that change comments behaviour.

I disabled all plugins - and this problem is still there. I don't know why that title is there - I don't see it on other sites powered by WP+Atahualpa including my own.

Posts don't have subtitles.
With Atahualpa you can display a kicker, the post title, a byline, the post and a post footer - are you talking about one of these?

Yes, I am talking about post title.

It is added for some reason before the comments section. Right after the number of comments - without even a space added.

This glitch persists even with all plugins removed. I didn't edit theme of WP core.

Did you create a PO file with the translations? did you add a blank after 'коментарі' in the file?
