Satollo newsletter v2.5.2.7. problem

Hi everyone,

I have installed and configured the plugin and I’m able to send a test-mails and receive it back by pushing the [Send a test-mail] button in the config.page. So far so good. But when I try to save an email witch i made in the email-composer page, the form just turns blank as if i press a reset-button in an email-form.

– I’m not aware of problems with my IE(safety) settings.
– Firefox does the same.

BTW:
The multisite seems NOT to be the problem because it works fine in another multisite network of mine.

Someone an idea ?

Thanks.
