Website stops working when I create all variables from attributes

[ Moderator note: moved to Fixing WordPress. ]

I am building an estore with WooCommerce store theme and when I try to create all variables from attributes my site looks up and stops working. I contacted tech support for my site host and was told we don’t support WordPress we sell it and provide the server. I changed my PHP settings to increase max upload variables, max time, and several other settings and the issue still continues. HELP.
