Redactor I source button no longer working? Running Craft CMS 2.6.2903 and Redactor I 1.1.0

This is my config:

{
    "buttons": ["format", "bold", "italic", "lists", "image"],
    "plugins":["fullscreen", "source"],
    "toolbarFixed": true
}


fullscreen and source no longer work, not sure but possibly a recent Craft update? I have all my rich text fields set to Rich Text (Redactor I) and Standard as Standard.json is the config I edited for above settings. No html or source button shows up, fullscreen shows up but doesn't work.

Anyone know what could possibly be wrong, this config worked a while back.
Updated the files, still didn't work, clicked uninstall, then installed again and its back, not sure what happened.
