Hi everyone,
As title says, sometimes adding to cart does nothing - not even a pop up window with confirmation of it opens up. I sometimes manage to test-buy something with newly created users, but after that order buying from that user doesn't work anymore. Can't buy anything with unregistered users either.
Tried everything basic - cleaning cache, cookies, etc.
Also tried incrementing AUTO_INCREMENT value in ps_cart (answer written here https://www.prestashop.com/forums/topic/392573-solved-empty-cart-problem-1609). Doesn't change anything.
Shop url is http://www.avesa.lt/ ( if you test it, try buying something from section 'Perkamiausi' under 'Populiariausi Pasiūlymai' ).
Theme is called 'Wiser Pets Store Template'
I'm at my wit's end here guys, will appreciate any help.
EDIT:
The debug mode on the site is always turned on, because whenever I turn it off, Back Office crashes and becomes unavailable. Could the main problem be related to that?
