Any Plugin setting -> You do not have sufficient permissions to access this page

Have you checked file permissions?

https://codex.www.ads-software.com/Changing_File_Permissions

I have this permissions :

/wp-admin/-> 755

/wp-admin/options-general.php -> 644
/wp-admin/admin.php -> 644
/wp-admin/tools.php -> 644

[No bumping, thank you.]

Can you replicate the problem using the default 2012 theme with all plugins deactivated?

[No bumping, thank you] -> excuse me but i still waiting for 3 day for reply.

thank’s esmi for reply,

i have activate Twenty Ten theme, desactivate all plugin

after that, i have activate only akismet plugin, go to akismet setting i get :

wordpress >> error

You do not have sufficient permissions to access this page

i have activate Twenty Ten theme

Why Twenty Ten and not Twenty Twelve?

do it just now with the Twenty Twelve theme, same result

problem fixed by using a new wp-config.php
