Lessons Error?

TumpaiTubo
In the “Positional Play” lesson, challenge 4 of 5: When it asks me to castle king side, it will not allow the castle. I can’t figure out how to get past it. Any help is greatly appreciated.
TumpaiTubo
Thank you, but I tried it. I then got out, went back through the lesson and tried again. It gives me the bad move buzzer.

odd...

TumpaiTubo
No, I cannot castle queenside, as the Rook is moved to a8.

can you link the puzzle?

TumpaiTubo
I’m on my iPhone, and I do not know how to link. Any help is greatly appreciated.

is it possible that your king is in check? you can't castle out of check. if your king needs to move thru check to during casting, you can't do that, and if the square where you are trying to castle is attacked by your opponent, then you can't castle. hope that helps :-)

TumpaiTubo
Thank you, but in the lesson the king is not in check.

I tried again and still can’t make it work. How do I share the screenshot or lesson from my iPhone?

Hello, it is probably a bug please make sure you have the latest version of Chess.com or have a relatively new version.

I’m going to clear my cache and try again.

Clearing my cache didn’t help, and my OCD is going crazy ... I’ve tried every move I can think of, and I failed. Maybe I’ll get back to it someday.

Hmmm, that's odd. It's probably just a bug. I suggest skipping that lesson, as you can always revisit it later. Is it happening to all of your lessons, or just one?

This lesson, right?

has the White pieces. White has pressure on the semi-open a-file. Can you find a powerful positional move that adds more pressure to the a-file and strengthens White's bishop on the long dark-squared diagonal?
 Hint Can you find a surprising queen move that strengthens both the rook on a3 and bishop on b2?
Qa1 Great job! White's queen strengthens both the rook on the a-file and bishop on the long dark-squared diagonal. Grandmaster Rubinstein retreats the knight, trying to relieve the pressure on the dark-squares. Let's trade Black's important defender of the king - the dark-square bishop!
Bxg7 White already has a strong positional advantage. Should White improve the position by castling or try to grab a pawn on a7?
O-O You're playing Grandmaster positional chess! White brings the king to safety, and prepares to play Rb1, taking advantage of the pressure on the semi-open a and b files. Reti went on to win a beautiful game.

Once you have gotten the answer, it won't let you retry the challenge.  I think you just have to go back and redo the whole lesson...I'm wrong a lot....

TumpaiTubo
Yes! ... but it won’t let me castle. I cleared my cache, restarted, tried the lesson again, repeated, and then I tried every move I could find. It will not let me castle. It buzzes like an illegal move. I’ve not seen the last message you posted.

Probably a bug on the iphone app then.  I was obviously able to do it on the browser (using Chrome, for the curious).  Try Help>Report a bug.  The mobile apps do seem to get a lot of complaints on the forums.

Baddogno: Thank You!
