2 XHTML errors in W3

I have 2 errors in W3 validation that have something with RR. How can I fix it?

-------------------------------------------

1. Line 453, Column 7: document type does not allow element "h2" here; missing one of "object", "applet", "map", "iframe", "button", "ins", "del" start-tag <b><h2>Domaći Filmovi</h2><p id="relevant_replacement">Ispod cete naci listu vez ✉
   The mentioned element is not allowed to appear in the context in which you've placed it; the other mentioned elements are the only ones that are both allowed there and can contain the element mentioned. This might mean that you need a containing element, or possibly that you've forgotten to close a previous element.
   One possible cause for this message is that you have attempted to put a block-level element (such as "<p>" or "<table>") inside an inline element (such as "<a>", "<span>", or "<font>").
2. Line 453, Column 55: document type does not allow element "p" here; missing one of "object", "applet", "map", "iframe", "button", "ins", "del" start-tag …ovi</h2><p id="relevant_replacement">Ispod cete naci listu vezanu za <b>Domać ✉

b cannot hold a heading tag.

remove the B

Headings are auto-bold on most browsers anyway so its not necessary.

I did but it didn't fix it.

What is the code you are using for RR's

<!--VBSEO_RR_1-->
<h2>[forum_title]</h2><p id="relevant_replacement">Ispod cete naci listu vezanu za [forum_title] forum na SerbianForum.org.</p>
<h2>[thread_title]</h2><p id="relevant_replacement">Ova tema je vezana za <em>[thread_title]</em> pod forumom [forum_title], i deo je foruma [parent_forum_title]</p>
<!--VBSEO_RR_2-->
[parent_forum_title] - [forum_title] na SerbianForum.org

There is nothing wrong within the RR templates

Than W3 have problem

You still have <b> tags around your relevant replacements. As Brian explained to you , you can't wrap h tags with <b> tags.
