May be this can be related to Windows HTTP server settings? It is better if you could use *nix based server.
Try to uncheck ‘Use slash arguments’ setting on the Server --> HTTP --> admin page.
Also Check your config file if it has any extra space??? If it has any extra space make sure you remove that.
Perhaps, but i run apache on win2003 server. there is no use slash arguments setting.
the dl.ph has no white space, config files neither.
I'm completely lost...pdf, txt it all works fine
.doc, .docx are the only files who look corrupted.
