Hi,
I've bought the AcyMailing component for Joomla. They have a MAtukio plugin which is great, but it is broken now (last updated in 2016). I've contacted them to ask for bug fix. Could you please provide them a recent version of matukio? (They asked if I can provide, but I think this would not be the right way).
You can reach them at: support@acyba.com
Thanks,
Marci
