@adavis-sdx It looks like one of your dashboard widgets is causing an issue, to test try going to another URL like dcim/racks/ and see if that works. If that does you can reset the dashboard by going to extras/dashboard/reset/ do note that this will reset any custom dashboard widgets you have set up.

Thank you all the left hand downdowns work if i go to dcim/racks/ and navigate from there
everything works apart from the home page by the looks of it.
I tried that dashboard reset but unfortunately it does not resolve the issue.
Thanks though for the suggestion.
