New version breaks WooCommerce Bookings

And what about v6.4.6?

That one is also broken.

Same console error?

I just checked. Yes. The console error on 6.4.5 is the same as 6.4.6.

Is it possible to have the calendar link?

Sure thing. https://flathead.mystudioengine.net/shop/booking-all-blocks/

This site is not running Category Colors 6.4.6. It needs an update.

Sorry about that, still had the old version when I was checking the console error. It should be back to the latest.

Can you try https://github.com/afragen/the-events-calendar-category-colors/archive/develop.zip to see if this finally fixes the error?

Please let me know.

Yeah, that appears to have done it. The calendar is back and the error is gone.

Thanks. A release will be forthcoming.
