I am having the same issue. I tried in Firefox, but still could not click on the tabs. Basically nothing happens when I click on them.
I also have the same issue when I’m creating template groups. I can create template groups fine, but I can’t click on the template group name to switch to different groups. The rest of the CMS seems to be working fine although I haven’t gotten very far into the development.
Running ExpressionEngine 2.8.1, downloaded on 5.19.2014
I did move my system folder up outside of the root as stated in the best practices if by chance that might have anything to do with the issue.
Seems like maybe a lot of js isn’t working in the CMS. “show sidebar” does nothing. “show toolbar” does nothing.
When I open up firebug I do see some js errors…
ReferenceError: _ is not defined
...var b=a(”#idle-modal”).dialog({autoOpen:!1,resizable:!1,title:EE.lang.session_id…
it references line 377…In the file it looks like a lot of jquery UI stuff, but not sure if this is related.
