You do not need to disable plugins all enabled plugin is needed for the site. We can’t see any error in the console. It’s a bug in the theme you should have a look at according to me. Since everything worked until update of the plugin. As earlier mentioned a staging site wont reflect the reality did you read that part? Or might have been another ticket. But since we have such setup you can’t duplicate paid license plugins. I won’t buy another cdn domain, wild card SSL certificate etc for you to debug disable plugins. And I don’t see disable plugins being necessary here. Jump links should work as normal.
If we setup a staging that will be 70% of the reality which is no help for you. When you think you know the issue and then you don’t since it’s not the reality.
Let me know when you have a solution to suggest. And I know you don’t need to disable plugins. Are you a developer?
