Solution for this topic
I have tested it on my test site and it’s working fine for me using latest version of Jevelin theme as displayed in the attached screenshot.
Please make sure that you have set Footer Template to Default.
If it still doesn’t work for you then would you mind if I log in to your site and do some troubleshooting? If this is ok then could you please temporary share me your site admin log in details privately by adding them in the box having text “Enter your private content here (only you and forum moderators will be able see it)”?
