I use the plugin Platinum SEO on my blog, and discovered that I made an error in almost 2000 posts. On the option "PSP Meta Index and Nofollow Tags:" of the plugin, in many posts, I did chose "noindex,nofollow", instead of the correct "index, follow".
So, I would like to know, please, how to change this without to edit each post, one by one. Maybe through phpMyAdmin.
I would be very grateful for your help. :)
