This module is very easy to implement, and the algorithm used to verify local keys can easily be modified into other languages.
I can't find an option to limit the versions available to a license like WHMCS uses for their owned licenses. Once a client stops paying for updates, they shouldn't be able to run a newer version than the last they paid for.
This used to be a great addon. While the basic functionality is still present, there are a lot of issues that WHMCS seems to ignore. The last update was ages ago and every time I report something they tell me they'll take care of it 'soon'.
It throws 500 errors on some reports, doesn't properly show actions in the global activity log and looks like it was created over 5 years ago (which I believe it was, together with the last update).
Thanks for your review. I hope you've been enjoying version 2 of the Project Management Addon, with a more contemporary UI and some popular features requested by users; including staff notification emails.
