I tried to install the following plugin that diplays related posts :
I ran the setup script to create the required a full text database index but it did not work.
As explained in the readme file, I then used PHPMyAdmin to
execute the following command :
wp_posts ADD FULLTEXT
But all I got is this error message :
#1061 - Duplicate key name 'post_related'
May someone help me ? I don't know how to solve this problem.
