Found a new error:
Catchable fatal error: Object of class WP_Error could not be converted to string in /home/dandrago/public_html/wp-content/plugins/wordpress-seo/frontend/class-frontend.php on line 867
Line 867:
$canonical = preg_replace( ‘^http[s]?
‘, $this->options[‘force_transport’], $canonical );
Clearly related to canonical issue.
