Bug 26471 has resurfaced following a DataTables upgrade, and now we have a warning in the console from Bootstrap too: Source map error: request failed with status 404 Resource URL: http://127.0.0.1:8081/intranet-tmpl/lib/bootstrap/bootstrap.bundle.min_24.0600036.js Source Map URL: bootstrap.bundle.min.js.map
This doesn't seem to be an issue anymore
