After upgrading from Moodle 2.8 to 2.9 I noticed some issues with the Atto Editor. I uninstalled it and then re-installed using the Atto editor from Git-Hub. Everything seemed to install OK, including all the plugins I had previously installed, but when I go to Plugins --> Text Editors, I no longer have the Toolbar Settings, nor do I see it when I click on Manage text editors. The TinyMCE options are all there. When I switch to Atto as my editor, I see the basic tools, but no more. The Collapse button is missing as well.
Any ideas of what I might do to fix this issue?
