Thanks for your quick reply, I will contact Avada support.
Dear Mike,
Thanks for your response. I think my theme (Avada) does style the .button elements, because at the checkout page (http://diamondtraining.nl/checkout/) the button is styled. Furthermore, before the update the button on the cart page was also styled. I tried emptying the cache. In addition, I’m not a programmer so custom CSS is out of my field of experience. Do you have a suggestion. Hopefully I do not ask to mucht.
Kind regards,
