Getting 404 Error In Admin from Extensions

Question

I am using Magento v1.8. I am trying to install extensions by using Magento Connect Manager. Everything works fine till the installation of the extension. But the Moment I click on the Extension via System > Configuration > Extension it gives me a 404 Error Page. Evertime. It's happening with every extension. Please let me know what should I do...?

Answer 1

This is standard Magento behaviour. Log out and log back in so that the acl can reload.
