This morning I released v0.39 of my WordPress Google Form plugin. This update addresses the corner case exposed when using WordPress Google Form with the Unite theme from Paralleus. To solve this incompatibility I’ve introduced a new short code attribute called unitethemehack which defaults to off. By turning it on, WordPress Google Form will modify the Google Form HTML to protect the Submit button(s) from being manipulated by the Unite theme.
You can find this update in the WordPress plugin repository or as an update on your WordPress Dashboard.
