Or maybe that's because of problem with create.arduino.cc, right? As I said, it appears last time very often (last weekend and today). But not all the time. And of course I did't change names, links, etc.
Everything worked fine for several months. But now this problem really hinders me. It seems that I have to stop using Create for sharing sketches and post them directly to the blog. This is more reliable.
right now I do not see this problem
