I have already generated the certificate. I have got a crt file and a ca-bundle file. Which file to copy and paste in the SSL/TSL page? How to open these files?
You can open the files with any text editor. Notepad works fine for that, but any other plain text or code editor can be used as well.
You’ll want to copy the contents of the CRT file (not the CA bundle) and upload it through the control panel.
