Thanks for this. I am still trying to understand why this error is appearing, especially at the times you receive it. Are you having users register without producing the error?
I one of my add-ons I have a few different spots where I display banned user information. On both templates the "end_date" value shows as "1714190400". In both templates I am using <xf:date time="" /> to display the value. In one instance the value does not change based on the visitors timezone...
The core idea behind the moderator panel is that moderation isn't binary and data can help moderators make better decisions. For example, knowing an user is ignored by X number of users may drive a decision on the severity of a punishment. Another feature is the ability to set users as protected...
I will add that I am running 2.3.0 Beta 4 and exporting a style from that server that was originally created in 2.2.X and importing into 2.3.0 Beta 4 has the same problem.
Do you already show a value for the users registration country or were they registered before you updated the add-on to capture country? Do they show a registered country now?
