[Plugin: WordPress SEO by Yoast] home page title not showing up

Did you try this code?
<title>
<?php
if(is_home() || is_front_page()) {
echo bloginfo("name") . ' | ' . bloginfo("description");
} else {
echo wp_title('', true, 'right'); } ?>
</title>

Let me know! They really do need to redo this plugin alot ??

SuperFast, can you specify please where to add that code? Inside the settings of the plugin from dashboard or inside the script itself?
For example, on my blog, check it to make a picture – Game-Stalkers ,everything beginning with the home page, post or pages contains twice the blogtitle in the URL. It’s really annoying, but the plugin is great for the rest of its abilities.

Should be in the file;
/wp-content/themes/(your selected theme)/headers.php

Thank you very much SuperFastCars! Have a great day!

Thanks.
