I’ve been able to recreate this issue with a clean installation of WordPress using the default theme. Steps after installing the Events Manager plugin:
- Create a new Event Category.
- Copy the “View” link for that category and log out, or open the link in another browser where you aren’t logged in to WordPress.
- At the bottom of the category page, all comments on the blog (from other posts, etc.) will be displayed.
I’ve only noticed this issue when viewing a specific category. It does not appear to show up on the “Categories” page and it does not happen when you are logged in to the WordPress admin area.
I am using WordPress 3.4.2, and I have tested this without any other plugins or custom themes installed.
