[For 1.8] MyIPB theme

[eNvy]

I've checked the code on localhost, is the same code as the default theme and it works for me (for some reason it doesn't in your forum).

You can search on the nav template if the code is the same as this:

<a href="misc.php?action=markread{$post_code_string}"><i class="fa fa-check fa-fw"></i> Mark site read</a>
