I noticed this issue on several sites and from searching your forum I think there is no resolution yet, is that correct?
I also just want to check before I add the css code you suggest in the below topic that this css code does not prevnt the box appearing with a message when it should appear, after the form has been submitted?
The issue has been already fixed in the latest version of X/Pro theme. I would suggest you update your theme and plugin as per our version compatibility page. Please make sure you have a backup of your files and database before you update the theme. It would be best if you could copying your live website to your staging area. then update your theme and plugins as per our version compatibility page.
In case if you have not seen our doc of theme update please have a look at it.
If it doesn’t work for you, please share your details in a secure note. Please provide the following details
