The input has been URL-encoded, so it looks like:

ode1 = {y''[x] + Sin[y[x]] == 0, y[0] == 2, y'[0] == 1};

Where it should contain:

ode1 = {y''[x] + Sin[y[x]] == 0, y[0] == 2, y''[0] == 1};

The

*NDSolve[]*invocation which follows this erroneous input understandably complains. Of course it does this in an unintelligible way.

There is more than one equation on this page with the same affliction.
