To install the SSL, please follow this steps:
1. Go to your Cpanel and look for SSL/TLS Manager
2. Generate the CSR (by clicking on Generate, view, or delete SSL certificate signing requests) which you will need to pass this to the SSL provider
3. Upload the CRT (by clicking on Generate, view, upload, or delete SSL certificates.) which you will need to key in the CRT that is generated by the SSL provider
4. Install the SSL (by clicking on Setup a SSL certificate to work with your site.) which will install the SSL for you automatically. You should see CRT, KEY, and CABUNDLE filled with some random numbers automatically so that the SSL will work flawless.
If you have any problem, just open a support ticket and we will be able to provide the SSL and install the SSL for you :)
