I installed and enabled the module. When I put an ISBN or a OL code in {{}}, nothing happens. It just displays the {{}} with the numbers. I have [full Html] enabled, WYSIWYG disabled.

Looking at my particular installation, we have Multisite and I am wondering if $path = drupal_get_path('module', 'bookpost') is calling wrong for multisite?

Otherwise, I am stumped. Any ideas?
