How can I remove rel "nofollow" from a widget_text? I'd like to try a solution without install a plugin. Thanks.
It sounds as though a plugin or theme function is already adding 'nofollow' to the widget, so it might be a case of needing to remove a plugin not add one.
It might be being added in your Theme's functions file with the following function: wp_rel_nofollow
You could try searching for that function thought your plugins and themes.
