Text inside the checkout field is not enter or hidden

Consider a theme update. I can’t say if that will fix the problem but its a good thing to try first. The current version is 3.8.3.

I m using 3.2.6 version. How to get this 3.8.3 version.

v3.2.6 is WooCommerce. I think your theme is evolve v3.7.6 and the latest v3.8.3 is here:

I upgrade the evolve theme and did the same still not able to add details while checkout as new customer.

The problem is coming from your theme so I think a theme update was worth trying. The problem is that the text colour is white on a white background. You can overwrite this theme style with this custom css:

input[type="text"] {
  color: #000 !important;
}

Custom css can be entered at:
Dashboard > Appearance > Customise > Additional CSS

Have a look round the site at any other input boxes to make sure they are alright.

Now its working but email address on the checkout page is still shows hidden.

input[type="email"] {
  color: #000 !important;
}

Thanks. Now it is working. Now tell me how to integrate shipping details at checkout form for the user. I m not able to do that. It is showing in the backend.

There’s a problem with your shipping address.
Please return to the merchant and update your information, including your city, state, and ZIP code.
This error is coming after checkout with paypal.

I’m sorry I don’t know about that one. If no one else chips in, you should start a new thread for a different problem.

Thanks
