When I want to install module, it will redirect to "Page not found"

[kevin0929]

I have downloaded module zip file, and I unzipped it in the modules folder.

But when I want to install module from admin page, it will redirect to “Page not found” and say “The page you are trying to view does not exist. Use the back button to return to the last page.”

Please help me!Thanks!

What URL is giving you that message?

And also, does this happen with all modules or just a specific one?

My URL is this photo print, in front of /admin is my domain.

Yes, it happen with all modules.

Thank you!
