Remove some items from setup tab

Make another admin role where you ban access to these items. Then set this new role on these admins.

Sometimes less knowledge bring us disastrous events.

I put FA 6 month for trial use, trial users did many things from hacking password from backup SQL file to changing system default settings. There are some absences in user permission part that does not meet my needs:
1-    Trough back up file anyone can access Hashed password and can set the Admin password to “password”
2-    Second admin can create new company and be able to make access to whole system.

The installed_extensions.php determines the default company - do not make the default company the active company for real accounts.

Also hide links in config file setting for inaccessible menu items.

If you want to completely hide menu items that are not accessible for a user, you need to edit config.php and change
$hide_inaccessible_menu_items = 0;
to:
$hide_inaccessible_menu_items = 1;
But you may find that the theme you want to use does not use that config setting and still show the inaccessible menu option regardless. Default and dashboard themes work, but elegant does not. I expect because elegant was written before the config option was added.

1. Export existing company and view the sql and note the table prefix - say ("0_")
2. Create new company and mote it's table prefix to be say ("1_")
3. Edit the sql from step 1 above and replace the table prefix with that of the newly created company
4. Restore the edited sql into the newly created comapny
5. Restore the sql/en_US-new.sql file into the default first company and change the admin password
6. Set the $hide_inaccessible_menu_items = 1; in config.php

Use the newly created company as your real company.
Use the default company as the control company.
