I have 2 Phore wallets on 2 different block heights and also different from the block explorer at
https://chainz.cryptoid.info/phr Is something forking or is it on my side?
Tried to delete the blockchain and resync but still not ok...
There isn't any forking. Be sure you've latest wallet. 1.5.x won't work as there was mandatory wallet version (1.6.x) released a bit ago.
That is, the use of the old version of the wallet 1.5.x is strictly prohibited?
I was not updated, but I understand this is a must.
Yes, you must update your wallet and synchronize it with the blockchain.
Using outdated versions of the wallet can cause problems.
My synchronization constantly freezes and I cannot download the entire blockchain.
