Calls not showing in Calendar after Upgrade

[dugjohnson]

I upgraded from 5.6.12 to 5.7.6 last night. All seemed to go well, but this morning the client reports that Calls do not show up in the Calendar.
Meetings DO show up

There are no messages in the logs that are pertinent to this.
If I create a shared calendar, the calls appear there.

I need some direction as to how to proceed to debug this. Where should I be looking?

Hi Doug,

Weird. Does this happen to all users?

It would debug this way:

1. Open calendar.
2. Open developer tool (F12) > Network tab.
3. Click next/previous buttons to initiate API requiests.
4. Here's the method that generates a query https://github.com/espocrm/espocrm/b...ities.php#L951

Thanks for that information which will be helpful in the future.
For THIS problem...I just figured it out and was coming to post my find.
Someone, somewhere in the past set the color in the /custom/Espo/Custom/Resources/metadata/clientDefs/Calls.json to #ffffff, so the Calls were there, but white on white. Changing the color and rebuilding fixed it
