Hi @muhammadaleemkhan
Thank you for sharing the form!
I was able to import it to my test site and when I tried to submit it – using pretty much random data in the fields – it all went fine and the form was submitted without errors.
It would suggest then that the issue is either specific to the site itself (e.g. due to some conflict) or only happens with certain type of data filled-in.
That said, could you start with conflict test? Basically:
– disable all other plugins temporarily, keeping only Forminator enabled and switch theme temporarily to Twenty Twenty-Two or Twenty Twenty-Three
– try submitting the form
– if it works, enable your original theme back and try again
– if it still works, start enabling plugins back one-by-one, after each one submitting the form; at some point it should stop working again and the last enabled plugin right before that would be the culprit.
Let us know here about test result, please, and we’ll then see what to do next to get it fixed.
Kind regards,
Adam
