Hi,
It's a problem with the customization done to the cart module.
The product row has 3 columns but the footer has one column with a colspan of 3 and a second column for a total of 4 columns.
The problem is that the value of the colspan is incorrect with the way you setup the cart module. It should be 2 not 3.
So you need to report the issue to the developer who did the customization there.
The colspan is calculated with the line:
$colspan = $nb_columns - (empty($columns['delete']) ? 1 : 2);
in the view file product / cart.php
So you could add the code:
after it to patch the calculation of the colspan.
Note that if you change the settings of the module in the future, that patch might become incorrect.
