We have two different boxes, both running 10.13.66-16. In both we get a JS error on the Time Conditions page and the Submit button is not working. One is an old box with existing time conditions, the other is a new one where we cannot add any time conditions.
The error we get in both (in both the main Time Conditions page as well as in the Add Time Condition page) is:
Moment Timezone has no data for Europe/Athens. See http://momentjs.com/timezone/docs/#/data-loading/.
We tried changing the time zone through Sysadmin-Timezone, through Advanced settings as well as on the Time Conditions page itself, but no matter what we select, the page will not work.
From what I can understand it seems to be a FreePBX problem
We can create Time Conditions from the lightbox pop-up in Inbound Routes (but cannot edit them afterwards).
Also, we have obviously tried this with multiple browsers (Chrome, FireFox, IE) and from different computers.
