There is no links manager in the admin_menu of Wordpress 3.5.1 anymore. I'm creating a custom add_links_page, and I'm having a hard time with the making a plugin.
Do I need to initialize something to show the links page?
It's commonly activated through:
add_filter( 'pre_option_link_manager_enabled', '__return_true' );
Link Manager plugin only contains this code line.
Or go in you wp database, in the (wp_)options table find the option "link_manager_enabled" and change the value from 0 to 1 (option_id should be 86)
