what did you updated exactly? What we would like to suggest is to deactivate all extra plugins and remove all custom css. We didn't changed anything in theme files related to Contact Form 7 plugin so it couldn't happen because of theme update.
Anyway, if above suggestion will not change anything, please go to your FTP, remove theme files and upload the newest one via FTP as well.
