I have tested it on my test site and it’s working fine for me using latest version of Gillion theme.
I can see you are using older version of theme on your site so please update it to the below latest version of it as described in this page https://support.shufflehound.com/updating-theme/
Please login to access this file
If the issue still persists then would you mind if i log in to your site and do some troubleshooting? If this is ok then could you please share me your site log in details privately by adding them in the box having text “Click here to share private content. Only you and forum moderators will be able see it.”?
