Edit wp-youtube-lyte.php
Try comment out, so double dashes are working again. Dont know why this plugin made this.
`if ( apply_filters( ‘lyte_kinda_textureize’, true ) ) {
// replace remaining double dash but restore it in comment tags (this is getting ugly though).
// $the_content = str_replace( array( ‘ — ‘, ‘– ‘, ‘ –‘ ), ‘ – ‘, $the_content );
// $the_content = str_replace( ‘<! –’, ‘<!–‘, $the_content );
// $the_content = str_replace( ‘– >’, ‘–>’, $the_content );
}`
