Thank you, wpfan1000 and graphical_force.
I tried the last option from wpfan1000 of adding the following to my custom css:
#optin2 .clear {
clear: none;
}
That seems to have done the trick.
But, I’m going to save the other option from you, graphical_force, just in case I need it.
Thank you both so much for the help. I can’t believe that I spent the entire morning on this.
