Report don't work

Hello!

Sience 3 Weeks create/send Piwik v2.6.1 no Reports (HTML/PDF) per Mail. I click on Download manually, nothing happens.
When i change the Email settings manually from local mail to locally SMTP Mail Server, nothing happens…

I this a bug or my Error?

canyou please try with 2.7.0 beta where this bug may be fixed? Index of /

Nothing else after update to v2.7 b4. I change the Mail Option to locally, nothing else…
There is a log file on error on Schedule Reports?

I click on Download manually, nothing happens.

When nothing happens maybe there is an error logged in the server error log file?
