Selenium nodes not working

All my selenium nodes are not working; nodes are red and it seems there is no way to run.

No explanation, no error message.

If i drag a 'startt webdriver' node in working area, I can't figure how to strat it.

Until past week every nodes works fine.


Anybody can help?

The StartWeb driver node now has a required input and needs a prior WebDriver factory node for configuration. More information is available in the nodes' documentations.
