this happens when i login to web explorer:
Warning: You are most likely on a fork (base target is very high).
this happens when i click on forging (my coins are on block 93000) :
Your effective balance is zero, you cannot forge. (Effective balance is your balance after 750 block confirmations).
whats wrong here?
The fork message is due to a bug in the wallet, it has been stated this will be fixed in a future release.
The message about forging means exactly what it says. You cannot start forging until your deposit has 750 confirmations.
