I'm using theme version 1.8.2 of Graphene.
Site appears normal and operates correctly but in the backend I have previously installed widgets in the sidebar and footer and now I cannot edit them.
If I go to widget editing page, where you normally click the little down arrow on the right of each widget area to show what it in that area, nothing happens when I click it. It does not slide open. I can't open the widget area to edit the contents. I can't drag widgets either.
Why would this be happening? Other features on the site work fine, for example, I can edit the menus in the normal way.
Yes I know it's not the latest version but I tried updating the version and the same problem occurred. When I updated I overwrote some theme changes I made earlier so I reverted to my backup until I can create a child theme to preserve my customisations.
