Can′t approve or delete 2 comments

Can you replicate the problem using the default Twenty Twelve theme with all plugins deactivated?

Are you still having problems with those 2 comments Rodomanes?

Yes, though i haven′t tried de activating all the plugins, have to try that one, but i′m open to other suggestions if that one won′t work ??

I tried to disable all plugins and delete, doesn′t matter, i still can′t delete those two comments.

And changing your theme?

This problem was before i changed themes, so the theme isn′t the trouble.
