There was a ticket here: https://support.dplugins.com/form-and-textarea-in-php-or-shortcode-breaks-editor/
along with a few others, but I couldn’t login to the support system last week and had to create a new account.
It looks like the old tickets and my old account are gone.
Hello sorry to hear that.
I can not find it either.
Can you please explain us how to reproduce the error.
