I am making a product page that has a product with multiple options for height and width in a dropdown. When I more than about 40 options, the page wont save them anymore. The page will just say
Invalid Form Key. Please refresh the page.
I tried refreshing the page, clearing the browser cookies and cache, clearing magento cache and clearing values in web/cookie/cookie_domain and web/cookie/cookie_path in the core_config_data table. I've tried different browsers in incongnito mode and they all seem to fail once I try to add to many values. Here is my webpage with some of the values. https://buyglass.woodstove-fireplaceglass.com/pyroceramic-glass.html Has anyone had this happen to them before, or have any other ideas on how to fix this?
