All colors gone after changing one categorie name

I confirm it’s a nasty bug !

Let you a message on github :
in settings when your categorie title (not the slug…the title) is like “Balade à Paris” the title in settings do not appear because of the accent on the “a”. It does work fine with “é” or “è” and that make the color desapear completly on front end when you try any update !

??

Just a thought, you might try adding ?refresh_css after the URL of the calendar as the CSS may be cached.

I think you will have to open a ticket on WPML and see if there’s a solution on that end as it is WPML that is changing the category slug and causing the issue.

Some searching found this is a common issue.

May some of the following links will help.
