Contact Form 7 Checkboxes

Love the theme! I seem to be having a problem with the checkboxes in CF7. When I insert them into my form, they appear like the attached image (Lines, not boxes). Here’s the code CF7 is generating for me. Am I doing something wrong?
[checkbox* checkbox-743 “Windows” “Siding” “Roofing” “Coating”]


Hello there,

I hope you are doing well today.

Please disable any third party plugins that you have active then reload the page to see if that helps.

Could you please provide a link to your website so that I can inspect it?

Best Regards,

I’ve disabled them. Doesn’t seem to help.

Hey there,

I hope you are well today and thank you for your question.

You can try achieving this by adding the following CSS code in the Custom CSS option of your theme on the below path.

Admin Area -> Appearance -> Customize -> Additional CSS

/*show check box*/
div.wpcf7 input[type="checkbox"] {
  -webkit-appearance: checkbox;

Best regards,
