Question attachment image size exceed limit allowed by configuration

I know this issue seems to recur, and have tried what I can.
I've made sure that the avatar image max size and the file upload max size , and the image upload size are all identical.
I have checked my main menu link to the forum id of type menu item alias


I would be grateful please for a pointer what to try next.

Thank you
