The config.json looked like it needed some more variable strings in the json list. I added a few strings to the config.json. I am mining kawpow and while updating the config.json variables that update in realtime in mining software while running i hit the right combination and hashrate on the mining software went up by 500%, its not displayed on zergpool current mining it does reflect on the income hashrate actual rate to GHS!
I will let it mine for the next 24 hours and see if the income is included with the display of like 1000MHs on average by radeon rx 580 sapphire
