In order to use the Vultr whmcs module without any problems, you must first complete the setup by following the steps on the Vultr module page. (https://www.vultr.com/docs/vultr-whmcs-module)
Let’s assume that you have performed the steps here without any problems. Now, even though the products are on your site, customers cannot order servers from your site and use the existing one. here I will try to explain to you how these errors are solved and how they are used without any problems.
Step 1- Open the vultr module and come to the products you added (yoursiteurl.com/adminpanel/addonmodules.php?module=vultr&mg-page=products)
In this area, we need to automatically get the default configurations of the product through the module to the system.
we need to click on generate default in both marked areas and add the adjustable options to our site.
When the process is completed, we can follow the steps below.
Step 2 Click the configuration button next to the products and go to the configuration options section that comes by default for the products.
Step 3 – You have to update each of the options (image, backup, Os type, app.) Here.
Now the transaction is complete, customers can use Vultr products from your own website without any restrictions.
I wish you good work.
