I’m experiencing “There has been a critical error on this website. Please check your site admin email inbox for instructions” error when trying to open EDIT option of a certain form alone. The settings, entries and other fluent form options of that particular form is working. The form is not loading in the page to which it is connect via short code.
I’ve noticed this issue comes up only when I let a client access the form using GET PARAM enabled.
WordPress version 6.1.1
Active theme: Björk (version 0.1.10)
Current plugin: Fluent Forms (version 4.3.22)
PHP version 8.0.25

Their support team is very good and quick to answer EVEN IF you’re using their free version. I don’t see a reason to not reply to someone who has a pro license.
When the critical error appears, there’s a link that goes with it. Click the link and follow the instructions.
