 * I updated the woocommerce plugin from 2.0 to 2.1 and it started showing these
   warnings:
 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ‘wc_setup_product_data’ was given in /home1/
   harris/public_html/mysite/wp-includes/plugin.php on line 507
 * Warning: call_user_func_array() [function.call-user-func-array]: First argument
   is expected to be a valid callback, ‘woocommerce_reset_loop’ was given in /home1/
   harris/public_html/mysite/wp-includes/plugin.php on line 507
 * I have tried searching everywhere on the support page and couldn’t find any solution.
   Tried to rollback to previous version, didn’t work since the database was already
   updated.
    Right now my whole plugins page is acting up and not letting me make
   any changes there. The warnings are showing multiple times on both front and 
   backend im guessing. I do not have recent backup of my database which i could
   rollback to get rid of the changes made by 2.1.2 and 2.1.3 versions. Is there
   any solution to this thing out there? any way to rolling back to 2.0.10 version?
   and rollback the database changes? Appreciate a response. Thanks
