OJS 3 bootstrap 3 not working

Hello all,

I’ve managed to download and install Bootstrap Theme to our test OJS 3 installation (Code version: 3.1.1.4; Database version: 3.1.1.4; Latest version: 3.1.1.4) so we can start working on migration, but the theme options are not showing.

Please empty cache a couple of times from Administration menu and log out and log in.

Hello all,

No changes… I cleaned up cache from the admin and manually at command-line…
