What do you put for the `-rpcallowip` option? That's literally what the error says there's an issue with but you don't mention it at all!

Either you or other software (GUIminer maybe?) must have written that config option to bitcoin.conf.

I think that I fixed!, I found the -rpcallowip in "open file configuration".
But now I have "IO errors 1, tolerance 2" when I start to minning.
