Same problem here, mr. @Babak ... and I solved by restoring WooCommerce v8.4.0; release 8.5.0 has some kind of incompatibility with new Porto Functionality v3.0.0, which comes with Porto v7.0.0I think this is due to the fact that I updated woocommerce to 8.5.0, and for this I need to update the port theme
If anybody can solve the problem in new WooCommerce, kindly let us know. Many thanks!
