I have been able to create a calendar topic, and the calendar shows up properly.

But, when I try to reply to the topic, I get a 500 error each time.

I have tried:

- initially wanted this in a subcategory, but got a 500 error when posting a reply
- creating a category with no subcategories, same error
- deleting the category and starting over with default settings in the category creation panel, same error
- using just one date and not a range, same error
- setting the start date time and end date time in the calendar plugin settings, same error
- not using a title above the date
- adding a space between the title and the date
- using only `[calendar] [/calendar]` in the topic with each on a separate line, same error
- doing the same but putting a space between `[calendar]` and `[/calendar]`, same error
- enabling a category calendar on the category, same error

I don’t know what else to try!

I have looked in [Creating and managing calendars](https://meta.discourse.org/t/create-calendars/283773), [Category Calendar with defaultView="listNextYear" not showing events](https://meta.discourse.org/t/category-calendar-with-defaultview-listnextyear-not-showing-events/231209), [Discourse Calendar - How to?](https://meta.discourse.org/t/discourse-calendar-how-to/165536)

I can’t reproduce this on a latest commit

Can you try it in [safe mode](https://meta.discourse.org/t/53504?silent=true) with these boxes checked:

Also, do you see any errors in the dev tools console when the post fails?

Is the plugin up to date? I believe there have been some recent commits to it.

Unfortunately same error when running in [safe mode](https://meta.discourse.org/t/53504?silent=true) with those settings.

I’m getting this error in the console:

Calendar plugin version:

But, I’m wondering if I need to upgrade to 3.2 - we had to delay our upgrade, but it’ll happen this Wednesday so I could try after that and see if it works?

Yea let’s try that - I suspect the latest plugin update needs the latest core version. There have been quite a few changes in core since 3.1.
