CheckOut page field text view issue

Hello,

On my site http://www.huttma.ro I have an issue on the Check Out page: the field text is having the same color as the background no matter what color I will choose. When I try to modify the color and I save my desired color the effect will be vanished as soon as I will leave the builder.
Also many glitches are on the other pages. i.e. on my Shop when I click on a product the new page with that product is opening but is not loading the full content of that page. I have to move to a new tab in browser and then to come back to my website tab to see all the content of the page.
I delete all the cache, tried on different browsers and mobile with the same result.
I deactivated one by one all my plugins but the issue is still present.
Could you please check this and maybe you could help ?

Thank you in advance.
