Plugin creates invalid markup

Hi,

The plugin creates an invalid markup if the content contains ” (quotes).

I updated line 29 in wp-last-modified-info/includes/frontend/schema.php

from

“text”: “<?php echo preg_replace( ‘/\r|\n/’, ”, strip_tags( strip_shortcodes( $post->post_content ) ) ); ?>”,

to

“text”: “<?php echo preg_replace( ‘/\r|\n/’, ”, strip_tags( strip_shortcodes( wptexturize($post->post_content ) )) ); ?>”,

Thanks,

Dirk L.
