Hi, sorry for the late reply — I didn’t set myself up to receive email notifications. That’s been rectified.
The cause of an ‘undefined index’ notice from PHP, in this particular case, is a request for a value from an array $metadata['pb_bisac_subject'] which is empty, or not defined. At the bottom of the page ‘Book Info’ there is a text field with the label ‘Bisac Subject’. Putting a value in that field will prevent the PHP notice from appearing in your log files.
funnymonkey, thanks for identifying an issue with the filterPlugins() function in PressBooks Textbook. An update, v1.0.6 is now available that should resolve the issue. If it doesn’t, and further issues can be identified as the responsibility of the PBT plugin — please feel free to use the support form on the plugin page http://wordpress.org/support/plugin/pressbooks-textbook or open a ticket on github https://github.com/BCcampus/pressbooks-textbook/issues?state=open
