We have problems at the moment with Vodafone’s new mobile optimising technology. This takes a page and tries to fit it onto a mobile phone screen. It does this by pretending to be a more competant browser in it’s HTTP headers.
However, in faking the HTTP headers it also strips out the WSSE authentication that Lifeblog uses for it’s security, meaning that each post will fail as unauthorised.
There is currently no easy work around for this except to change network or to register your site with Bango as they are apparently whitelisting sites to bypass this new proxy.
