There are no services available for the period you selected.

Hello,

This is caused by the way you have defined the hours.

You have multiple types of hour definitions:
12.00
13.00
14.00
and
12
13
14
The only way to define your hours is hh:mm so it should look like this
12:00
13:00
14:00

When you have everyday available you have a single availability interval but once you receive a booking the plugin doesn’t know how to update the availability intervals in the database with the hour definitions you are using.

After you update your hour definitions and submit availability again, everything should work.

Thank you
