Minecraft Villager no longer trade?

My Villager no longer trade in Minecraft. I traded a lot and now they don't have the offer anymore. Somehow it must be possible that they trade again. I play in version 1.15.2.

Just have to wait for a Minecraft day, then you feel like it again.

Is the offer gone or do you block it with the red X?
If the latter is the case, you only need to buy one of the newer offers. This will make the old ones accessible again.

Villagers need access to their respective professions, then they can fetch new goods and trade again. Every Villager also needs his own professional block, two blacksmiths can't share a block. Waiting for a day is no longer an option.

It doesn't work. Do I have to buy so much until the bar is full again?

No, only once his latest offer and then close the trade menu. Usually particles then rise and all trading options are opened again.

But there are always many villagers at once. They all take up the profession. Nobody gets their own block.

Not correct.

Every Villager has his own professional block, which they have to work on so that the offers can be activated again.

Apparently it has been revised a bit. At the bottom of the version overview you will find the entry under 1.14 that Villager now replenish their goods twice a day insofar as they have access to their professional block. So I refer to picasso22's answer.

They need it to fill up their goods. Without it, the trades will not be free again. Believe me, I only had the problem 2 weeks ago.

Does anybodyn know how to fix this, my farmer wants to trade 1 pumkin for 1 emerald, he is in stock, and when i pu the pumkins in the trading place, it says trader does not want this.
