Are you logged in as the administrator? Make sure you're logged in, via the "Sign in to edit this site" link (in the default template the link should be at the bottom of the page). I know it's a simple thing, but I know that I personally make silly mistakes like that sometimes.

If you're not logged in as an admin, you won't see the toolbar.

Thanks. I had been logged in as admin (only account created). But when I got in to check one more time I saw there was an upgrade to 5.3.1 and installed it. Now I see the toolbar! Don't know what the other issue was but I'm in now. Thanks.

Hello!
The concrete5 toolbar is empty. /login admin/
I use linux mint 13, with java 7. Tested on the java site, the java test was good.

On my friend mac os x the toolbar is ok, just on my linux.
I know it is a system problem, but the java is ok, and I try firefox, and chrome is same.
Just a blank toolbar.
Can you help me what is missing on my linux?

I just developed the same problem, which appears on only one of my Concrete5 sites, constitution.org. Another site, pynthan.org, on the same host using the same version of Concrete5, works okay. The disparate behaviors appear the same using any of several browsers on either Linux or Windows. I changed the password for the admin user, and it works. It is almost as though the admin user has lost admin privileges.

This was a one-click install at dreamhost.com. My version is 5.4.1.1, although I see the current version, on pynthan.org, is 5.4.2.2. I will try upgrading on that and hope the upgrade doesn't break admin access.

Upgrading to 5.4.2.2 on both my other Concrete5 sites, paleodining.org and pynthan.org, worked, and the admin toolbar appear when I log in as admin. Since they are on the same host as constitution.org, and only that site exhibits the problem, I have to ask if there are some files I could copy from the directories of the working sites to the nonworking one to try to fix the problem.
