I am using typo3 7.6.14 and powermail 3.10.0 with default configuration. First i just installed the extension as described in the docs. In Frontend after submitting the form the page is reloaded but nothing else happens.
I have to say that i am working on host europe server at the moment (php 5.6.29). On my local machine same code works (php 5.5.27). the form is submitted and a short message is given to the user. but on live server nothing ... On live server "send test mail" via install tool works.
Maybe it is a general problem about hosting. Any ideas?
