 * Hi guys,
 * I did an update last night to the new 3.6 and I’m currently using woocommerce
   too. I have now got an error
 * Warning: call_user_func_array() expects parameter 1 to be a valid callback, function‘
   woocommerce_price_filter_init’ not found or invalid function name in /var/sites/
   c/carbonworlduk.co.uk/public_html/wp-includes/plugin.php on line 406
 * I have read through many other threads regarding this error and one thread suggested
   I deactivate all plugins and the reactivate until I find which plug in is causing
   the problem. I deactivated all plugins and it did go but now I have lost the 
   cardsave payment details and the site is all muddled with no categories just 
   the sub categories.
 * Please can someone help as this is my business and I’m losing money!!
 * Thanks

 * First of all, when doing an upgrade, make a backup, especcialy if you are running
   a business.
    2. are the first problem solved? Did you find your plugin that was
   causing the trouble? 3. can you give the link to your site?

 * Hi, Thank you for your reply.
 * In future I will make a back up. I’m not great with computers as you can prob
   tell. Can you recommend the best and easiest way to make a backup.
 * No the plugin issue hasn’t been sorted. I had the original developer who hosts
   the site restore it back by 24 hours.

 * That should be a line of code below
 * `add_action('init', 'woocommerce_price_filter_init')`
 * inside one of your theme files. Find that file.
 * This is a duplicate call and is what has been causing the error. Comment it out
   or delete that row as it is a duplicated call.

 * Hi,
 * Thank you for your info. I have since reverted back to the old site by restoring
   the site but I still have many plugins including the wordpress site which needs
   updating. I have had a look for
 * add_action(‘init’, ‘woocommerce_price_filter_init’)
 * And found it here:
 * add_action( ‘woocommerce_before_main_content’ , ‘yiw_woocommerce_ordering’ );
 * // add the sale icon inside the product detail image container
    remove_action(‘
   woocommerce_before_single_product_summary’, ‘woocommerce_show_product_sale_flash’,
   10); add_action( ‘woocommerce_product_thumbnails’, ‘woocommerce_show_product_sale_flash’);
 * // active the price filter
    add_action(‘init’, ‘woocommerce_price_filter_init’);
   add_filter(‘loop_shop_post_in’, ‘woocommerce_price_filter’);
 * // add body class
    add_filter( ‘body_class’, create_function( ‘$classes’, ‘$classes[]
   = “shop-“.yiw_get_option( “shop_products_style”, “ribbon” ); return $classes;’));
 * Obviously I don’t have a problem with the site right now but i don’t want to 
   mess it up again with updating all the plugins.
 * Regards
