Hello osama al nimri and welcome to the Canvas Community! Are these discussion posts that you are typing and having disappear and not post to the boards? My first suggestion would be to type your response in a program like Word so that if you try again and the same thing happens, you can go back to your Word document and copy the response rather than typing it again.
You might try logging out of Canvas, closing the web browser, and then logging back in again to ensure that when you do this the post doesn't appear as it should. Also, I am not sure what web browser you are using, but would suggest trying in Chrome and FireFox if you have not already. Sometimes web browser does make a difference for some reason.
If you are still experiencing the issue, I would contact Canvas Support or submit a ticket using the question mark icon in the global navigation menu (normally the left side of your screen). Support may be able to give you additional suggestions or have insight into what is happening.
