Doesn't start paper tarder/ traderbot

[Ytigiev]

Then when I change to another tab like Backtest, I got these one :
Why a line, related to paper trader, appears when I click on Backtest ?

Because the backtester uses a plugin to simulate trades called the paper trader, which is different from the mode "paper trader", naming is confusing sometimes..

Please, see the attached file. I hope you will help me solve the problem.

That zip only includes the gekko watcher log. Is there another file as well with tradebot in the name?

No. 

Can you install release on your windows pc and test the latest release?

And which browser do you use for a testing?
