Can you please tell me, Atick, what changes you have made? The module (events all) which shows the events, no longer displays at all and I don't see any error message. It also does not show on the events page (english or french) . This is the module that displays all the events - it calls a js which makes an AJAX call to another database - but I didn't mention this before as I didn't think it was a factor here and would only confuse things. However, since the calendar link works separate from the module it does seem to be involved. I have inserted a simple text block before the module which simply has the calendar link in it and it works in both English and French so perhaps it is something to do with the call from the js , through the module to the SP page builder. You can see in ottawaotest.ca/oocj4 the module that is now missing in testj4. I will have to restore testj4 from oocj4 (or from its own backup) but first I would like to know what you have done to cause the event listing to disappear.
