Well I have looked at McAfee, I have the Internet Security Suite and no where can I find a place where there is a list called white list and black list. There is a place to add and allow IP addresses but not the web address so I'm sorry I do not know where to add wordpress.com where you are asking me to. As I said before, I apologize for my ignorance I'm new at blogging let alone trying to understand everything all at once and since I had not had any problem before and have been using McAfee al along and keeping it all up to date I was and still am at a loss as to where to add wordpress.com to a white list.
As of now, the uploading option is available and working so I don't know how it was fixed just glad to have it back.
