I am using number fields with format 9,999.99. If I enter letters or other non-numeric characters in any of these fields and submit, the form submits without validation error and no entry is made in the number field in the post.
I have switched themes to disable all CSS and JS and deactivated all other plugins to eliminate conflicts and problem persists.
Any thoughts on how to get the validation to work?
I’ve tested the number fields but was unable to replicate the issue you’ve mentioned. Could you please try to reproduce the issue on a fresh installation and then send me a screenshot?
