sorry for my bad english!
if I try to make a newsletter with the Composer, I always get an Error Message:
<title>503 Service Unavailable</title>
<p>The server is temporarily unable to service your
request due to maintenance downtime or capacity
problems. Please try again later.
But it is only with the Composer. So if I make a newsletter with HTML-Code, everything works.
I get the error if I click on the buttons “test mail” “save” and “next”. Always begin a download of an admin PHP with this error message.
Is it a problem of my service or should I wait until the problems are solved from the plugin support?
