I have recently set up a site using icagenda to manage my organization's events. We are a volunteer group, so I have embedded a shared Google Sheet into each event page for member sign ups. (I know that icagenda does event registration but my group prefers spreadsheets). This was accomplished fairly easily by creating a custom field for text and populating it with an iframe for each event sheet.

E.g.
However, if I enter the edit screen for an event, the content of the iframe is missing, and the field only has the following text:

So, every time I edit any part of an event, I have to fill in my custom field all over again, even if I didn't touch that field. Is this a bug? Is there anything I can do differently to stop this?

Thank you in advance!

Well, I just tried taking screen shots for you and now I can't reproduce the issue. Since this task involves accessing an external source (i.e. google docs), maybe there was some problem with accessing that content yesterday.

I will call this solved and keep an eye on it. Thank you anyway!
