all modules are locked.

Hello. I installed the demo. I'm trying to edit some of the modules and they are locked. I changed the settings in the configuration for the super user to allow and now it is showing locked near the allowed.
I did uninstall and reinstall and having the same problem.
Please advise.

Probably you have two user sessions active and this block the modules. The solution is very easy, please just follow this instructions » How to unlock modules or articles in Joomla – GavickPro Documentation
