When trying to send a test message i get an empty screen.
No entries in errror log.
I get this error since migrating to another server with same php version.
phpList Version: 3.0.12
PHP Version: 5.6.17
Browser: Google Chrome 48
I already tried it with another PHP Version (5.7) and with php safe mode off.
Solved by updating to phpList version 3.2.4.
