And can access home page after delete class.rlwp.php(zencart_demo_templates_1.1).

2. can't display products detail after switch language when i check one of products.and display:Warning: Cannot modify header information - headers already sent by (output started at /home/content/l/i/q/liqinghua/html/includes/templates/shop/common/html_header.php:25) in /home/content/l/i/q/liqinghua/html/blog/wp-includes/pluggable.php on line 865
