 * Hi,
 * Recently we seem to be having problems with constant PHP errors when in the dashboard,
   usually along the lines of:
 * Notice: Undefined index: addcart in ***removed***/wp-content/plugins/wp-ultra-
   simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 93
 * Notice: Undefined index: quantity in ***removed***/wp-content/plugins/wp-ultra-
   simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 142
 * Notice: Undefined index: delcart in ***removed***/wp-content/plugins/wp-ultra-
   simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.php on line 161
 * Warning: Cannot modify header information – headers already sent by (output started
   at ***removed***/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.
   php:93) in ***removed***/wp-admin/post.php on line 197

   at ***removed***/wp-content/plugins/wp-ultra-simple-paypal-shopping-cart/wp_ultra_simple_shopping_cart.
   php:93) in ***removed***/wp-includes/pluggable.php on line 1167
 * Sometimes this actually results in stopping the page from loading.
 * Any ideas what might be causing this?
 * We’re on WP 4.5.3 and the plugin is 4.3.9.2
 * Thanks
    Ben

 * Hi Mike,
 * I managed to resolve this yesterday but forgot to update the thread.
 * It got to the point where the dashboard was inaccessible due to the volume of
   PHP errors being generated so had to go in via FTP and rename the WP Cart plugin
   folder to block it from loading.
 * Anyhow, after disabling all plugins apart from WP Cart and then adding them back
   one at a time it seems to be an incompatibility with another plugin:
 * tPlayer – HTML5 Audio Player (with playlist)
 * Luckily we’re not using this plugin right now so it was fine to disable it and
   the PHP errors have now stopped occurring.
 * Thanks,
    Ben

 * Thanks for your feedback, I have to do tests tPlayer to see why it broke somrthing.
   
   Mike
