There is a bug in All In One SEO Pack that affects Canonical URLs of multi-page posts and pages which causes all sub pages of multi-part posts or pages to have the Canonical URL of the base page itself. This bug severely affects SEO of a website by preventing indexing of the sub pages.

There is an ongoing bug in the popular Wordpresss reCAPTCHA plugin WP-reCAPTCHA which causes the reCAPTCHA box to sit right on top of the Submit button, with no space between them at all. There is also another issue where the reCAPTCHA box is shown below the Submit button.
