I've inherited a Wordpress multisite install. I'm in the process of redesigning several of the subsites and I've noticed that Wordpress is not displaying the admin bar in the front-end, even as an admin.
Initially I thought it was a theme error so I went ahead and changed to a stock Wordpress theme such as twenty fifteen. This didn't work.
Then I thought it could be a plugin issue so I disabled all plugins as well. This didn't work either.
Then I also check if in the user profile I had the show toolbar option enabled, and it is.
Wordpress, themes and plugins are up to date.
I'm 100% sure it's not a plugin or theme problem, because I am not able to see the admin bar in any of the subsites. Thing is I've ran out of ideas regarding what it could be.
Any ideas what could be wrong?
