Working Hours broken! Plugin not working

We can't get the plugin to run on our site. We suspect this is due to the date format.

The Working Hours doesn't show AM/PM correctly. Here is a screenshot:

Even once you get past the confusion, once you save the values the booking form is broken. Here's what the booking form looks like:

NONE of the appointments are available. No matter what values you set in the Working Hours form. It also breaks the available values, often defaulting to 08-12PM it seems.

I can provide credentials to the site in a private message.

To replicate, you can download the Swedish package of WP from:

Then simply attempt to setup the plugin. I'll challenge you to get it to work. :slight_smile:
