[ESS] Error starting R

[Jeremie Juste]

Hello,

Can you specify the ess version you are using?

I would suggest disabling global-font-lock-mode (M-x
global-font-lock-mode) before launching R to see if it works.
It is not a fix but just a way to investingate where the problem might
be.


Best regards,

Jeremie
