# Your theme developper might have forgotten \</body>

Some theme developpers forget to add \</body> at the end of the body of your theme.

If \</body> is not there, the code of Cowlendar can not be injected and the app will not work. You will not see a button "BOOK NOW" on your product page.

The simple solution for that is to edit your theme and add \</body> at the bottom of the file.
