Hey,
I was trying to hook your filters with a theme I'm using and I noticed you're applying the filters in the wrong place. I haven't looked through the rest of the code, but here's a small fix I suggest:
Original
} else {
$format = apply_filters( 'msp_get_title_format', get_option( 'msp_title_other' ) );
$data = apply_filters( 'msp_get_title_data', $data );
}
Revision
} else {
$format = get_option( 'msp_title_other' );
}
$format = apply_filters( 'msp_get_title_format', $format );
$data = apply_filters( 'msp_get_title_data', $data );
This applies to lines 409-412 in the meta-seo-pack.php file.
Thank you for the great plugin that has been priceless for me!
