Field names not showing up on profile screen Wordpress CMS
This looks like a CSS issue.

I would suggest to create a new css file in you custom directory like /wp-content/plugins/files/civicrm/my_css/my_stylesheet.css Navigate to Administer->System Settings->Resource URLs and set your Custom css URL to the css file http://yoursite.com/wp-content/plugins/files/civicrm/my_css/my_stylesheet.css
more info on how to set a custom CSS path here.

In your CSS file put this:

.label {
   color: #000 !important;
}


The field names/labels are there but they have a white color.

I guess that if put the same style in your Wordpress theme stylesheet section it will override Civi's stylesheet, but the above would be the correct and recommended way to do it.
