Adding Category in home Page

We change the domain aladdinmart.com.au to http://aladincart.com.au/ Here it is saying purchase code already exist that is why i am giving domain as aladdinmart.com.au.

My problem is i want to list all the Product Categories in a page (http://aladincart.com.au/product-categories/) But it is not working i am using Wp Bakery builder and ovic category but it shows nothing.

If i am using default template a comment section is automatically added there. can you please suggest the way how can i use this

Thank you in advance
