Can you tell me the php file to remove the apps button? Thank you very much !

Server configuration
Operating system: Ubuntu14.04
Web server:OC9.1.3
PHP version:5.6
ownCloud version (see ownCloud admin page):
Updated from an older ownCloud or fresh install:
Special configuration (external storage, external authentication, reverse proxy, server-side-encryption):

ownCloud log (data/owncloud.log)

Please paste possible errors in the following code block, see for more info

Integrity status for oC9+

Login as admin user into your ownCloud and access
paste the results here.

There is a config.php setting for that [1], not need to modify code (the file you had a look was completely wrong anyway).

Just disable the gallery app??

The two buttons (gallery and apps ) are not visible and available in the admin mode.

Thanks you!!!!

Why not just create a new user?

The Gallery button is visible in the user mode. Thanks you for your reply!
