Just recently spirit theme has been showing some unusual issues on pages where the "essential Grid" plugin is in use, either using a shortcode or as a widget.
When logged as admin on a page using essential grid, it is impossible to start the upfront design/edit mode. you can edit pages with out essential grid in place.
Also, there is no output from essential grid whilst logged in as admin.
However, when not logged in as admin the grid displays properly.
I suspect some kind of clash with jquery but can't pinpoint it.
This has only started happening recently.
