Also the clean cart link sometimes not refreshing the mini-cart display.
Have to manually refresh screen to see that the cart is now empty.
This is the code from cart.php
<a class="hikashop_small_cart_clean_link" href="<?php echo hikashop::completeLink('product&task=cleancart&url='.$this->params->get('url')); ?>" ><img src="<?php echo HIKASHOP_IMAGES . 'delete2.png';?>" border="0" alt="clean cart" /></a>
This seems to work (I have changed my cart.php to only display minicart):
Click add to cart - minicart updated.
Click add to cart - minicart updated.
Click add to cart - minicart updated.
Click delete cart icon - cart deleted.
This does not work
Click add to cart - minicart updated.
Click add to cart - minicart updated.
Click add to cart - minicart updated.
Refresh screen (Ctrl-F5)
Click delete cart icon - cart not updated.
Refresh screen (Ctrl-F5) - empty cart now displayed.
