I dont know how to fix the opera channel. I have that installed on my wii but havent used it since may so for all I know I could be in the same boat as you. Dealing with your shop channel though, there was a system update nintendo had out that installed a new ios (ios61) and a new shop channel. The older shop channel used ios51 but that ios is no more so instead it uses ios 61. There is a download on this thread (just search for it) where you can download ios 61 and the shop channel. First youll want to install the new ios and then install the shop channel. The shop channel install will overwrite the old one.
