Changes the WordPress cookie path to root directory for root-level files that call functions from a WordPress installation under a subdirectory.
This plugin is most useful when you have your blog under a Web site whose pages use different WordPress functions that requires you to have logged in.
For example, you'd like to use the
wp_loginout(); function to display the login link whenever you are logged out and
the logout link otherwise on all pages of your site, but WordPress is installed under
/wp/ where your blog also
resides. Therefore, WordPress creates cookies under the
/wp/ directory only, making you seem logged out on the
directories above the WordPress directory. This plugin will make WordPress create cookies on the root directory of your
domain to eliminate the problem.
