John Tobey, great job with Abe. Thanks for sharing this work with the community!
I'm trying to set up a website with several altcoin block explorers. The first one I tried was Klondikecoin, this works already like a charm.
Now I'm trying Noblecoin, but get same error, same as
unick, just one post above.
$ python -m Abe.abe --config NobleCoin.conf --commit-bytes 100000 --no-serve
Opened /home/adversor/.noblecoin/blk0001.dat

After I have commented out the Merkle root verification in DataStore.py, it reads 214 blocks from chain and this is the output:

I'm using
default-loader = blkfile
Someone has a solution?
