Comment on Technical Support by SEO Dave.

WordPress Technical Support Sorry to hear that, quickest solution is login to your site via FTP (free program like Filezilla) and go to /wp-content/plugins/ and delete the /blog-comments-seo/ folder.

That will deactivate the plugin and solve the problem.

Looks like I missed a repeat function check on the above, will fix it next update.

Could also delete the /blog-comments-seo/ folder (or the blog-comments-seo.php: file in that folder) via some webhost control panels, if you have a file browser that allows deleting folders that would work as well.

Sorry about that, should have had that check in place.
