Display content module not working on new install

when debug mode is turned off, the Save button for the content module in admin does not work

when debug is turned on, it saves but I have issues with the module on the front end.
when clicking on buy now from the module, I get be below errors ( buy now form the product page works )

the url it directs to when clicking the module and displaying errors is: index.php/component/hikashop/checkout
where the products page url directs to: /index.php/hikashop-menu-for-products-listing/checkout


-- url of the page with the problem -- : mywebsite.com/mypage
-- HikaShop version -- : 2.3.1
-- Joomla version -- : 3.3.0
-- PHP version -- : 5.3
-- Browser(s) name and version -- : FIREFOX x.x.x
-- Error-message(debug-mod must be tuned on) -- :
Notice: Trying to get property of non-object in /home/web/public_html/shutter/templates/citylife/layouts/default/layout.php on line 15
Fatal error: Call to a member function get() on a non-object in /home/web/public_html/shutter/templates/citylife/layouts/default/layout.php on line 15

the issues of saving the module is with the template ( just tested a new install)
so I started agin with joomla 3.2.4 and template issue is ok but still have the same problem using the content display module

I think I worked out what the problem was:
if the Content Display Module is Not on the Hika shop page, the link to check out is incorrect.
but when on the product list page, the module works and links to the checkout correctly.

is this how it is meant to function? or is there a way to get the module to work on an isolated page?

Hi,

I think that you are talking about the cart module. To force a checkout page, you can set a value for the option "Force a menu on the checkout" in Configuration > Checkout
