Toggle Month (list) broken - solved

Does this issue only occur in 5.1.13?
What changes did you make before this happened?
Any errors or warnings in the log or browser console?

Hi,

Thanks, yes it worked in earlier releases.
The url of the page is https://www.festivalseekers.com/calendar

I am not seeing anything in the Console that is specific or the Drupal logs.

Still not enough information for me to know what happened to your website.

Given that, this version was released last year September and there are 8.5 thousand websites using this version currently. This is the first time I heard this kind of issue.

I would suggest that have someone with Drupal developer background to have a closer look at and debug this issue for you.

Particularly looking at any other module or theme that modifiers the template used by the calendar.

Fair enough.
I am not a 'Drupal Developer' per se but I have built and maintain dozens of drupal sites.
This is what I am seeing.

This is in a site running core 10.2.2 with PHP 8.1.27
When I installed Fullcalendar View this was a Drupal 9 site.

I suspect that issue may be related to the core 10.2.2 (just spitballing here)

I use Fullcalendar View on another site (still a Drupal 9 site) where it works just fine.
On this site, Fullcalendar View has been working fine until now, not sure why it is acting up, but it looks js related.

When I go into the view edit screen and make an adjustment to the Full Calendar Display Settings (Calendar display settings.
Left side buttons) then hit the apply button this happens. See the attached screenshot ( https://www.drupal.org/files/issues/2024-01-25/dc-left-side-button-apply... → ).It does not indicate that the change was made yet it seems to have been applied.

Here is a really interesting bit.
When I inspect this code in chrome (not logged in)
<div class="js-drupal-fullcalendar fc fc-ltr fc-unthemed" data-calendar-view-index="0" data-calendar-view-name="calendar_festivals" data-calendar-display="page_1" style="">

In the inspect window, I see the code actually strobing on and off. This is a first for me by the way.
See this screen shot (should be an animated gif)

This behavior also happens (logged in) in the views edit preview screen in Opera and Safari.
The admin theme is Claro.
The site theme is a Bootstrap 4 theme.

Is this helpful at all?

Well, found the problem.
It seems that there is a conflict with the Popup message module ( https://www.drupal.org/project/popup_message → ).

Sorry for the noise.

No problem. It is good to know that you are on track to fix it for your site.

Good luck.

Thanks,
The module seems to be rock solid.

But this is somewhat disconcerting

From the #6 post above.
