Before starting, make sure that your domain's Nameservers are pointing to Crucial. The easiest way to do this is to check your domain on ozdns.com.au The first nameserver should be either nssyd01.crucial.com.au or nssyd01.aumanaged.com or nssyd01.clusterdns.net
Step 1 - The first thing you need to do is to find the Wix DNS records. Log into your Wix account then click on this link: https://www.wix.com/support/html5/article/domain-pointing-records
The page should have the DNS records which look like this:
Leave that page open, then open a new page or tab and log in to cPanel (click here for a guide)
Step 2 - Click on the Zone Editor
Now click on Manage
You need to find and delete these 2 records:
Next, scroll up to the top and click on Domains
Step 3 - Click on A Record to add the first record
Add the record and click ADD an A Record. Note that a . will automatically be added to the end, this is fine.
Step 4 - click on CNAME Record
Add the record and click Add a CNAME Record
Now repeat that and add the last record
Once you've added all of the DNS records you will need to wait up to 4hrs for the DNS records to propagate and your site should be pointing correctly to Wix.
