Hi,

After update the BigBlueButtonBN from 2.1.8 to 2.1.9 I discovered the following issue: when the page "Edit setting" is opening, the wait icon “Loading …” is displaying in the “Select files” field and there is no way to download the presentation and to setting the Participants and other sections. In Chrome Console there is the error:

TypeError: Cannot read property 'name' of undefined
    at Object.participant_add_to_form (yui_combo.php?m/1495001771/mod_bigbluebuttonbn/modform/modform-min.js:1) …
Please, help to resolve this problem.

Sincerely, Sergey Kinash
