Like XenForo 1.x itself, add-ons for XF 1.x are in support mode. This means that they will receive bug fixes until May 31st, 2019 and security updates only until December 31st, 2019. They are feature locked and no new features will be added. As of December 31, 2019 they will be End of Life and no further support will be given after that date.
If you have obtained any of my premium add-ons from another site, you DO NOT have a valid license for those add-ons and no support will be given to you. The only place that can sell licenses for my premium add-ons is this site.
