I use Joomla 3.5.1 and Sendy package ver. 1.0.4 . Until few months, this module used to work. Now after filling the email field and then pressing the submit field, both module fields disappear, only the module title is showing. No feedback is showing. Any idea?
My guess is that there's something wrong with the directory you've set for Sendy and that we aren't able to communicate with their API. I'm not aware of any issues with the Sendy integration itself, so all I can figure is that a setting is wrong somewhere due to some change.
Double-check the Sendy URL in our plugin and all other settings. If that doesn't help, let us know a URL where we can see the module and we'll gladly try to investigate further.
I agree, since 3.5.1 (probably 3.5 too) the module doesn't work anymore, the post response throw a : Application Instantiation Error: Could not connect to MySQL.
It need to be updated to Joomla 3.5 and i didn't find what change by myself ...
