We have a Wordpress multisite 4.2.2 RPM installation on CentOS 6.6 and in the network plugins panel, the add plugin button and the plugins updates are not showing up (100% sure some plugins are not up to date).
The odd thing is when heading to /wp-admin/network/plugin-install.php, it says we haven't sufficient permissions to access the page. Note that we have a superadmin account.
So far, we tried to comment the config line define( 'DISALLOW_FILE_MODS', true ); and changing all the salt in the config ... no luck.
We tested our server connection to api.wordpress.org:443 and planet.wordpress.org:443 without any problem.
Also note that we have a second WP installation on the same server (not multisite) which is working as intended.
Any clue is welcome, thanks !
DISALLOW_FILE_MODStofalse(ie. not just commenting it out, but setting it explicitly to false) - how aboutdefine('AUTOMATIC_UPDATER_DISABLED', false);Can you add the full content of wp-config.php (commenting out your sensitive information obviously)? - Mikk3lRo
