Reply To: Upgrade under WP v4 = prob;ems with imagick?

@ Vince

Looks like your host offers Imagic, which is good, but it seems they must be using a pretty old version if that method does not exist, which is bad.

You can try to ask them to update it. here’s a code snippet that should do it:

Another solution is to remove Imagick support from Connections.

add_filter( 'wp_image_editors', 'vince_remove_imagick' ), 9999 );
function vince_remove_imagick ( $editors ) {

    if ( ( $key = array_search( 'CN_Image_Editor_Imagick', $editors ) ) !== false ) {

        unset( $editors[ $key ] );
    }

    return $editors;
}
