Hello,
I follow all steps regarding creating product. But when I go to Frontend, I got following notices :

Notice: Undefined property: stdClass::$BeforeDisplay in C:\xampp\htdocs\trial\components\com_k2\templates\default\category_item.php on line 22

Notice: Undefined property: stdClass::$K2BeforeDisplay in C:\xampp\htdocs\trial\components\com_k2\templates\default\category_item.php on line 25

Notice: Undefined property: stdClass::$AfterDisplayTitle in C:\xampp\htdocs\trial\components\com_k2\templates\default\category_item.php on line 80

Notice: Undefined property: stdClass::$BeforeDisplayContent in C:\xampp\htdocs\trial\components\com_k2\templates\default\category_item.php on line 108

Notice: Undefined property: stdClass::$AfterDisplayContent in C:\xampp\htdocs\trial\components\com_k2\templates\default\category_item.php on line 157

Notice: Undefined property: stdClass::$AfterDisplay in C:\xampp\htdocs\trial\components\com_k2\templates\default\category_item.php on line 293

What should I do avoid it. Please guide me.

You should turn off error reporting in production sites.
These are notices and will not affect your site's functionality in any way.

Furthermore are you using K2's latest version?

Hello Krikor,
I've checked for turn off option in Configuration, but I couldn't found it. Am using joomla 3 and K2 v2.6.8

Hi. The option is named "Error reporting" and you have to set it to "Simple" ( or "None" for a production site ).
