I am using RL Tabs now. So the issue was not with jwts_tabber. And the error code is still:

bootstrap.bundle.min.js:6 Uncaught DOMException: Failed to execute 'querySelector' on 'Document': '#4-explore' is not a valid selector.

When I see '#4-explore' is not a valid selector I assume the issue is with BS4 and nothing to do with RR or RL Tabs.

Do you agree?
