I have been working on developing a Magento site and today the little plus signs beside the categories on the
Manage Categories section of the admin side disappeared.
I can still use
Expand All to expand the category tree, but it is more difficult to navigate the categories this way.
Any insight into why the plus signs would disappear?
When the categories are expanded I still have the little minus sign to collapse them, but no plus signs.
Any help would be appreciated.
