I installed selfoss on the freehoster lima-city.de
After some starting problems selfoss is running now.

But I cannot add sources. I cannot even open the "add sources"-dialog.
If I click the sources-button in the lower left corner a popup-box appears with the text:
"Load list error: Forbidden"

All other buttons are working fine - as far as I can see.

edit:
I seems, the error only occurs, when I try to connect form my office via proxy.
If I use a dircet connection (e.g. a monile device) it works fine.
