SuiteCRM values are not displayed on the contact page

Hello,

SuiteCRM version 7.5.3 is successfully installed and I have a wp plugin “SuiteCRM Customer Portal” installed.
Plugin Link: https://wordpress.org/plugins/sugarcrmsuitecrm-customer-portal/

On creating a new Contact, the contact is added but values are not displayed on the contact page.

I tried adding a contact using the code attached below and the result is the same and database table has NULL value stored.

How do I solve this?

Thank you

did you follow the SuiteCRM side process of enabling this?

best regards

The plugin says on the suitecrm contact page the custom fields have to created which is done.
Is there any configuration that has to be done on suitecrm?
