Hi Elie,
The developer gave me the solution yesterday ??
This is a bug in the functions.php file.
You can fix it immediately by adding just one line of code.
Inside the title filter function, at line 83, just paste this code:
if ( is_feed() ) return $old_title;
That should be pasted just above this line:
$site_name = get_bloginfo( ‘name’ );
And that’s it.
You may have to force refresh your browser/reader to see the change.
