I have been having problems with my permalinks for my site. I use pretty much all the plugins you guys have (Ultimate, Affiliate, etc.) My problem is that when I go to Product Category page I get a 404 Page not found error. I have now been through and tested my theme, tested all plugins by deactivating all except Woocommerce and the problem occurs as soon as I activate WCFM.
I have tested it twice now and both times it was as soon as I turned on WCFM.
