I have a problem with the Atto editor in Moodle 2.8.3, only the Collapse button is showing.
The configuration is as shown in the example below on the page:
style1 = title, bold, italic
list = unorderedlist, orderedlist
links = link
files = image, media, managefiles
style2 = underline, strike, subscript, superscript
align = align
indent = indent
insert = equation, charmap, table, clear
undo = undo
accessibility = accessibilitychecker, accessibilityhelper
other = html
I can remove the collapse button and get it back, but I cannot get any other buttons to show.
