Error While Posting

I don’t know if this is a problem with the forum or an operator headspace problem.

I was creating a post. After getting well into it, I made some modifications and tried to do a cut and paste and got this error:

AFAIK I was not requesting to use a resource but was only editing my post by cutting and pasting. Can anyone tell me what I did wrong so I can avoid it in the future? Once I got the error I could not continue to edit my post.

@ahraitch
Can you link the post for me.
