Please I'd appreciate it if someone replies this psot 'cos it's delaying the taking off of my blog.
Just yesterday I installed the YARPP plugin onto WordPress 2.8 but since I couldn't understand the codes, I immediately deactivated it. Now each time I go to the admin page to login a fatal error comes up that says:
"Fatal error: Call to undefined function is_site_admin() in /home/.mitja/electricscootersnaija/electric-scooters-guide/wp-content/plugins/wordpress-related-posts/related-posts.php on line 81"
Which means I can't login to post articles and stuff.
Please how can I get this resolved? Can it be rectified? Thanks for your help,
