Ok. I see the tabs now. Thank you everybody.

First, have I installed the extension correctly? This is what I get at "Install/Activate Extensions".

extension     |    installed    |    Available    |           
FrontHrm     |    2.4.0-3     |    Unknown    |    X

I created a new company and logged in as "System Administrator."

These are the options I found at "Access setup":

Sorry for typo. I had the module installed on fa Version 2.4.4 Build 04.08.2018

Thank you for responding, boxygen.

When I go to "Access setup", I couldn't find any item related to "Human Resource Management."

In any case, I ticked everything that is listed for the role "System Administrator."

However, after logging out and logging in again as "System Administrator," I still could not find the tab for "Human Resource Management."

installed and activated it on fa 2.2.4. but cannot find HUMAN RESOURES tab.

Using default template. Must I use another template?
