I was notified by a blog follower that the email she received from this plugin had an option for her to check the BCC - which has a drop down menu and allows her to see everyone's email that has subscribed to blog updates.
I haven't made any changes to the CSS and in fact just reset everything to make sure - and I hadn't made an changes.
I have no idea why this happened or how to fix this.
Please help. Thank you!
