Hi lorenzoat,
The email send form contains the words "delete" and "from" in it, and we've had reports of at least one server-side firewall that intervenes in that situation because it suspects an SQL injection attack. The content on the page is totally innocent ("delete" is used in the button that deletes attachments from the message, and "from" is used to indicate the sending email address) but unfortunately the firewall overreacts. There's not much we can do from within OJS except e.g. to rename the delete button to something more obscure. We've only heard of this second-hand, however, so I don't have any specific recommendations beyond investigating whatever firewall software you have. It's probably something server-side. There are other threads about this on the forum, and those might have more specific information.
That's assuming my diagnosis is correct, but I think it's likely.
Regards,
