You can get the Pro version of the plugin either by following the checkout process in our website or in the WordPress admin area, if you have the free version installed.
Here’s a video showing how it can be done:
Steps:
Choose your plan.
Complete the checkout process.
Check your email. The email with the upgrading details might be in your spam folder.
If you completed the checkout process in the WordPress admin area, consider the email will be sent to the site’s administrator email. Check if your site settings what is the email and if it’s a valid one.
If you didn’t get an email, you can get the details from the members area.
You should download the Pro version, which will give you a zip file that you can upload on Plugins > Add New > Upload.
After you enable the plugin, you should enter your license key.
