White comment text on white background hard to see

I apologize for not being precise in my earlier post.

Here is the issue that I am having. When a person has made a comment (non-Facebook or twitter), the color of the comment text appears to be a drop-shadow white font on a white background which makes it difficult to read the post comment. (See http://www.myphotographyhobby.com/test-post/).

In this example John Doe’s comment “This is a test comment.” is hard to see and John Doe’s name as well.

What I can do to fix this?

Any help would be greatly appreciated.
