I am trying to add a number of product variants for a particular product. Each time I add the variant options x-cart goes through the process of rebuilding the variants, which takes a bit longer with each option group I add. After adding the fourth option group it seems to get hung up on the rebuilding variant stage.
Is there a limit to how many variants can be added for a product?
I'm running an older version of x-cart. version 4.3.2
Thanks!
