Text fields are not working other than Email field

Hello,

We are using contact form 7 plugin on our website, but when I am trying to submit the contact form it is coming up with the error “One or more fields have an error. Please check and try again.”

The form fields are Email, Name(text field), Subject(text field) and Message(Textarea).

I tried to resolve the issue on my level and I found such a weird issue when I removed all text fields and kept only Email field in the form then the form submitted successfully, but when I added other fields than the form again started giving the same error.

Please suggest how can I resolve this issue, We will appreciate your help in this.

Thanks
