Ok, I will try to write down my situation.

I sent 1.275 BTC to one guy, but the problem is, that he can't see that transaction in blockchain.info, however, in the other websites, this transaction is visible.

I tried fixing it by Repairing my Wallet in multibit, after all the syncing was done, now it shows that I got pretty much the rest of my money unconfirmed, only like 0.01 is on the left side, where it shows confirmed money. Moreover, in the payment section, all the transactions are shown as being completed, and I don't know what to do, I had this kind of situation with unconfirmed money in multibit before, but I guess it got fixed by repairing the wallet, I can't remember that right now, because it was probably 1year and more ago.

Any help would be appreciated.

EDIT: I tried sending 0.0001 to his address again, it reached blockchain very fast, and it's confirmed already…
