Upgraded from version 6.0 to version 7.2, and now our workflow for content approval is not working. Any suggestions on how and what to troubleshoot? Before the upgrade we had module "HTML PRO" version 6.0.1 and after the upgrade the installed module is "HTML" version 7.2.0. Since the name has changed I am assuming other things have changed and may have broken something in our setup. None of the changes we make get saved, and no emails are sent to the content approvers. Where to start looking?
