Hello,

I get this error when i try to add product to the cart

Fatal error: Allowed memory size of 268435456 bytes exhausted (tried to allocate 105 bytes) in /home/xxx/public_html/wp-content/plugins/woocommerce/includes/class-wc-cart.php on line 609

I can give you the link if you need it. But, since it’s a live website, i cant keep your plugin activated.

Thanks
