I seemed to be having a similar problem with the contact form on my companies blog page. When I upgraded my wordpress theme Atahualpu to version 3.7.13 the 3, 4 and 5 positions on the contact form are now misaligned. The text box for someone to fill in their information now appears to the right of the label instead of underneath like the rest of the fields messing up the alignment. Here's our blog page so you can see what I mean.
I've been trolling through support forums and trying to fix it myself but haven't found out how yet. Anything suggestions would be greatly appreciated.
Thank you for your help,
