There is no reaction even if i click 'sell in market' button on my bot.

Only this items? Or all items?

Can you try with another browser?

That button pops up a new window for the set ask orders page, if that button worked before then probably the new window got blocked, or you can try completely clear the browser cache since the Ethereum update changed some scripts.
