To have your WordPress website having a contact form working, you need to do the following:
Until all errors or issues of WordPress are fixed, please make sure debug mode is true - enabled for that, you can take help of the wp-config.php file and steps as found in Google Search at
Using that, you will get real errors and issues, rather than blank pages. As that will guide you, what error is for which reason, and accordingly can be fixed.
Make sure to use SMTP authentication-based contact form plugin in WordPress where SMTP Details are requested and used by the plugin to have it working on your contact form backend on the website.
SMTP Details you need to use in such plugin are as follows:
from: any email id created by you for example something@yourwebsite.com
from name: anything there is fine up to you
smtp hostname: localhost
SMTP Secure - None
SMTP Port: 25
SMTP Auth = YES
Plugin tested & working fine:

Once done, please recheck your form now, probably will be working fine now. If not, please contact our helpdesk team at support@webji.services.
Kindly include a screenshot of your plugin settings filled by you + a Screenshot of the error message you are getting + a Text copy of the error you are getting when contacting our helpdesk team for support.
