If you have the same issue, instead of keep trying the same thing, try something else.
What I found works for me (after even logoff and signin again without success), I try to submit post and click in the [Clear] option below to start the post new.
If that still doesn't help, then sorry, I've no other suggestion other trying on a different computer.

Thanks much ! I will try . I also wrote to [email protected] and gigHub . Let's see what's the issue
