The Manage Groups page used to show a little icon you could click in order to see the child groups of a parent group. Now, under 4.7.6 there are no icons. This means you can't see or manage the child groups. This is a major issue for us. Any suggestions for how to fix this. Is it a bug?
As you noted in the comments below, there is a JIRA discussion about this issue. The issue has been tracked down, and a patch submitted (which is now in Q&A and slated for 4.7.8).
Per @jitendrapurohit on the Jira thread above:
Submitted a PR - https://github.com/civicrm/civicrm-core/pull/8323
1) First issue mentioned above was the regression of CRM-18184. Seems the patch attached on that was different from the PR submitted. This was later fixed in this PR https://github.com/civicrm/civicrm-core/pull/8020
2) Second point was a regression of this commit. The updated params loses the key('parentsOnly') sent from $_GET.
