I have re-activated the html suffix and it seems to be working fine for me here with the user that you provided. Can you provide us with your user account so that we can try to replicate the issue on your site?
i am also getting reports from users which are hitting a 404 error when changing ore trying to upload a new Avatar.
Strange thing is I cant seam to reproduce what users are reporting.
Friend requests should not actually appear under the notifications section. Friend requests will only appear on your friend requests dropdown. Can I know what does that notification item says and how can I see that particular notification?
Also, can you please report other issues on a separate ticket please.
back to first Problem. When user accepts friendship other user gets confirmation notification that friendship got accepted. This one redirects to profile of user which uses .html suffix when I delete .html in url the profile loads with out issue. Hence suffix problem.
