I have 2 wordpress installations
and i tried to change the url in the settings to domain.com/blog
while the site url is still domain.com
now when i try to log in to my root directory's wordpress
nothing happens when i submit the form...
What can I do to fix this?
Move your entire install to the new place you specified. Or, add these lines in your wp-config file:
define('WP_HOME', 'http://domain.com'); // no trailing slash
define('WP_SITEURL', 'http://domain.com'); // no trailing slash
which will get it to load back at domain.com (Assuming you haven't moved any files).
