Ошибки в админке (товары) Undefined variable

[EgorK]

Вот такие ошибки я вижу в товарах (в админке):
1.Notice: Undefined index: category in/public_html/admin/view/template/catalog/product_list.tplon line 113Warning: Invalid argument supplied for foreach() in/public_html/admin/view/template/catalog/product_list.tplon line 113
2.Notice: Undefined index: manufacturer in/public_html/admin/view/template/catalog/product_list.tplon line 114

3.Notice: Undefined index: button_clear in/public_html/admin/view/template/catalog/product_list.tplon line 114
 

Что на что заменить, что дописать? 

Помогите пожалуйста разобраться.
 

Вот кусок кода:
