Thank you for letting me know. I’ve just released version 3.7.8 which should fix the issue and works well with WordPress 5.6.
Thanks it works 🙂
And thanks also for the great work, it is a great and simple plugin!
Sorry, but for me the calender is still NOT working! I get the message (translated from German):
“Error on loading the calendar: undefinded”
@michavo73, that sounds like a different issue. The issue that @skariko described caused the calendar to be invisible, but it didn’t cause any errors.
When you see that Error on loading the calendar: undefinded error it normally means that you’re having a conflict with another plugin or theme. It also means that there will be an error in browser console. Can you please take a look and let me know what you see in the browser console.
@zgrossbart, I didn’t install any new plugin or theme. This error appears since the upgrade of WordPress and/or your plugin.
On browser console I got the following error:
Error loading calendar: TypeError: a.droppable is not a function
Do you need any further informations?
That error sounds like you’re getting an error with the jQuery UI versions. Did you upgrade any of your plugins or themes as part of upgrading to the new version of WordPress?
@zgrossbart, I have activated the automatic updates of WordPress. So it’s not that easy to say. I think I can remember that just before the automatic upgrade and afterwards a few updates were installed for plugins and the theme. How does this affect this problem and how can I solve it?
This error indicates that another plugin or theme may be replacing the jQuery UI libraries and that could be causing a problem for the calendar. Would it be possible to try disabling some of your other plugins so we can isolate which one it is?
@zgrossbart: Now I did what you suggested and I found the plugin that courses this error: “Meta Generator and Version Info Remover”. When I remove it the calendar is shown correctly. Now I prevent the WordPress version in the code with the ”
remove_action(‘wp_head’, ‘wp_generator’);” function in my function.php of the child theme.
I’m very interested in any annotations of you! 😉
That’s great work @michavo73. I’m glad you found it.
You might want to to reach out to the creators of those plugins and ask them to not inject JavaScript changes in the WordPress admin pages. It’s very likely that they will break other plugins as well.
Hello @zgrossbart , I am also facing issues with the plugin in WordPress version 5.6.
I upgraded the WordPress version, deactivated all plugins but Editorial Calendar, and I still receive the An error occurred while loading the calendar: undefined error with no other indication.
Even the browser console prints the undefined error without details.
Please note that version 5.6 proceeded with jQuery updates as mentioned in their release report: https://wordpress.org/support/wordpress-version/version-5-6/#jquery-update.
Can you please check this out?
Thank you in advance.

@luludak, have you upgraded to the latest version of the Calendar plugin? We did have an issue with the new version of WordPress, but was fixed in the latest version. You can see it working our test blog here:
http://www.zackgrossbart.com/extras/sandbox/wp-admin/edit.php?page=cal
@zgrossbart yes I have (version 3.7.8), WordPress 5.6, all other plugins deactivated and updated version via the WordPress UI.
Are you using a different theme?
I am using a custom theme, however, I did not do any changes lately related to the plugin or the jQuery versions. What jQuery/jQuery UI versions does the plugin utilize?
