Anyone could help me there?

Hello everyone,
This is Billy. I am currently running my wordpress site with the responsive theme. I had some problems and I need your help. My site is http;//www.vibeenglish.com
1.How do I make my plugin wp-pagenavi work with my theme since it doesn’t support this plugin? Or is it possible to replace the “older posts, newer posts” with page numbers like the plugin wp-page navi does?
2. It doesn’t work very well with woocommerce plugin if visitors are browsing my site by IE. How to solve this?
Looking forward to your early reply
Best regards,
Billy
