There is an error with your “redirection/rewrites” in nginx.
how do you access the webgui: www.example.com or www.example.com/somepath?
i think, that /media is missing. so no css, javascript & images files can be loaded.
I debugged the page with chrome and found some references to /media. The first reference to the stylesheet seems wrong, as I can’t find any folder called CACHE inside the media folder in seahub?
This seems to be unavailable. Is this a clue that could help solving this problem?
