 * An issue popped up today though no changes were applied on the site:
    [](http://digitalpopuli.com)
 * On the right sidebar, a warning message on the home page:
 * Warning: preg_replace() [function.preg-replace]: Unknown modifier ‘<‘ in /home/
   content/90/5110390/html/wp-content/plugins/page-links-to/page-links-to.php on
   line 186
 * Assuming this is the code it refers to:
 *     ```
       if ( $highlight ) {
       		$pages = preg_replace( '| class="([^"]+)current_page_item"|', ' class="$1"', $pages ); // Kill default highlighting
       		$pages = preg_replace( '<li class="([^"]+)"><a href="' . $current_page . '"', '<li class="$1 current_page_item"><a href="' . $current_page . '"', $pages );
       ```
