I activated the blog stats by W3 counter today after it had been sitting on my plug in page for a month or so. In a few minutes, my site went down with this message. I deleted the plug in file from my control panel on my server, but it didn't make a difference.
Fatal error: Call to undefined function: register_sidebar_widget() in /home/urant0/public_html/CarolSetters/wp-content/plugins/blog-stats-by-w3counter/w3counter.php on line 20
Would love some help with this - thanks so much.
