Fixes: #45
This PR refactors any instance of
get_plugin
to handle the fact that this could return boolean false, thanks to interference from 3rd party plugins. Unit tests have been updated to cater for the possible false return value.These changes only deal with the problem as it presents, the exact source of the problem is still unclear, and I'm waiting for a customer to provide access to a staging site so that I can identify the plugin causing the problem on production.
