That brought me here after 8 years. My account is still active although My Opera is gone.
I get "failed to transcode URL" message many times and some webpages become inaccessible. I use opera mini 4.5 and I have opera mini 3.2 and opera mini 7 on my mobile which I almost never use. When opera mini 4.5 gives above message for some xyz url, other 2 browsers give above message for same xyz url. So I think it is not browser specific problem. It seems Opera servers use my phone to keep track of all activities and it associates xyz url with my phone, not with opera mini 4.5, 3.2 or 7 which are on my phone. So when xyz url is screwed on server, it gets screwed on my all 3 browsers. Same xyz url works fine on non-opera browsers.
Whatever it may be, please fix this problem.
Thanks !
