Hello,
After upgrading to 1.4.3 from 1.3
i had to create some ES menus to preserve links that wasn't needed menu links before to work
ex :
in 1.3 .../profil/56-mike was going to mike's user profil
in 1.4 .../profil/56-mike is now pointing to 404
same for : app, activity log, search, conversation inbox, followers, friends... almost all menu items from the user dropdown menu

i have created the menu items, now it's work for me
If i's not a but, i's better to inform ES users that now they need to create those menus items to preserve their url...
