No worries Ronnie. Looks like my theme has redux embedded (probably an older version). I was advised to deactivate the Redux plugin. That fixed my issue. Thanks for you assistance, appreciate it.
Thanks Ronnie, i tried that but still get the same error when trying to access the theme settings. Do you also use Union theme?
Im having the same issue. I dont have the vendor support plugin installed. Just redux 4.4.4. The error happens when trying to access the theme settings. Im using theme Unicon.
