I cannot access the People page. There is no error message. If I click on People in the menu bar, the Administration home page is shown.
The other Administration pages are accessible.
Similarly, if I click on Permissions for any module, I get the Administration home page; not the Administration > People page.
The User module is enabled. I am logged-in as user #1.
I have checked the .htaccess file and do not see anything that would cause a problem.
I have tried disabling the handful of modules I have added.
What should I do next?
