While I am extremely grateful for the help, I am not comfortable giving admin access to someone I do not know, or cannot even verify is affiliated with Catch Themes directly. I would have uploaded a screenshot for you, but this forum doesn’t allow attachments.
I checked the Social Links section of the Appearance/Customization menu, and there is no setting there for turning the social buttons on or off, just spaces to add links and a setting for button height at the top. I tried turning off nearly all plug-ins, so we can rule out interference (though the social buttons worked fine on the free version with them all on). Only other change was upgrading from Catch Responsive free version to Pro.
If you can describe for me where to look, if you can think of anything which might prevent their displaying correctly, I’ll gladly go check there and let you know the setting. Or you can tell me what it SHOULD be.
Thanks so much for your help!
