Hello, I have found one bug in module tabs.
When you hover over date or K2 article displayed it is showing this text:

Here is the screenshot (but you can see this on your own demo page for SJ ExpNews):

Dear Sir

Please go to templates\sj_expnews\html\mod_k2_content\Sidebar\default.php and find:

<a class="moduleItemTitle" href="<?php echo $item->link; ?>"><?php echo $item->title; ?></a>

=> change to:

<a class="moduleItemTitle" href="<?php echo $item->link; ?>" title="<?php echo K2HelperUtilities::cleanHtml($item->title); ?>"><?php echo $item->title; ?></a>

go to templates\sj_expnews\html\mod_k2_comments\comments.php and find:

<a href="<?php echo $comment->link; ?>"><span class="lcComment"><?php echo $comment->commentText; ?></span></a>

=> change to:

<a href="<?php echo $comment->link; ?>" title="<?php echo $comment->commentText; ?>"><span class="lcComment"><?php echo $comment->commentText; ?></span></a>

thanks

Dear anhqn,
as always you have been there when needed with solution.
Your solution has solved issue with the Title of K2 article in module.
Now when hovering over date of creation I see error

but only over date. Everything else is fine.

I have provided screenshot bellow:

With kind regards.
