There are several common form submission errors that can occur on a WordPress website. Some of these include:
- Required fields not filled out: This error occurs when a user submits a form without filling out all of the required fields.
- Incorrect format: This error occurs when a user submits a form with information in the wrong format (such as an incorrect email address or phone number).
- File upload errors: This error occurs when a user tries to upload a file that is too large or in the wrong format.
- Validation errors: This error occurs when a user submits a form with information that does not pass the validation checks set up on the form.
- CAPTCHA errors: This error occurs when a user does not complete the CAPTCHA test correctly.
- Server-side errors: This error occurs when there is a problem on the server-side that prevents the form from being submitted correctly.
- Database errors: This error occurs when there is an issue with the database connection preventing the form data from being stored correctly.
- Security errors: This error occurs when a user tries to submit a form with malicious or unauthorized input.
These are some of the common form submission errors that can occur in a WordPress website, but there can be other errors that can occur as well.
