In the description for the plugin you have this line -
You will have to add the following to your marketplace language file. DEFINE( "VIEW_PROFILE", "View Profile");
My qustion - what language file? where is it?
Will this fix the problem that the other posts are asking about, because that happened to me as well. At least from what I can read it appears to be the same issue (I have trouble reading white text on a light gray background, that should be fixed).
