I checked the log file, it's countless repetitions of the following:
(ERROR) -- SDM.pyc:791 - ValueError in bkgd req top blk
Traceback (most recent call last):
File "SDM.pyc", line 765, in __backgroundRequestTopBlock
File "bitcoinrpc_jsonrpc\authproxy.pyc", line 105, in __call__
File "json\__init__.pyc", line 351, in loads
File "json\decoder.pyc", line 366, in decode
File "json\decoder.pyc", line 384, in raw_decode
ValueError: No JSON object could be decoded
Please help?
