server 500 update

Hi, we tested on different sites and it works, could be something specific in your site: can you find the error logs of your server where errors with code 500 are recorded in detail?

Ok, could you kindly send them to me at stefano at thenewsletterplugin dot com?

Update: the error (http 500) was not connected to the Newsletter plugin update, it was raised by another plugin during the update process.
