The posts_nav_link() function is defined in /b2evocore/_functions_bposts.php

Yes, but where is the one for the sidebar? I'm having problem translating the PREVIOUS | NEXT in the sidebar. I translated evey NEXT and PREVIOUS in the .po file but the one in the sidebar refuse to show in Arabic.

Please see the sidebar in my Arabic blog:

Thanks for your help.

It looks like the Kubrick2evo skin defines the words that go there in the sidebar, rather than letting the default translation come through. It should be easy to fix. Find this code in /skins/Kubrick2evo/_main.php:

<?php posts_nav_link( ' | ', '< '.T_('Previous'), T_('Next').' >' ); ?>

and change it to:

<?php posts_nav_link(); ?>

Thank you personman,

It worked and I need to ask you one more favor.

Where is CSS class to control this. I used this code:

<h4><?php echo posts_nav_link(); ?></h4>

But no matter how small I make h3 fontsie. It does not seem to affect it.

This should work:

#bSideBar h4 {
font-size: 50%;
}

Also

<?php <h4><?php echo posts_nav_link(); ?></h4>

isn't right. It should be

<h4><?php echo posts_nav_link(); ?></h4>
