It seems you did not get what checkpoint I meant.
I'm pretty sure I understood :/
getcheckpoint
{
"synccheckpoint" : "000000231e3abea847919c620b5693a36b6e454923b42398db927387523a08e4",
"height" : 371800,
"timestamp" : "2013-12-23 07:38:54 UTC"
}
As mentioned above please follow the instructions I posted to remove the checkpoint error!!
This time it worked out, thanks. Strange that when I sync'ed a few days ago it did not help.
