Do these Related Posts plugins work solely based on tags?
The necessary plugins with wordpress are akismet and all in one seo...all the other plugins are depending on your theme selection..If your theme requires that you can not install the theme without that plugins..ex. wp page navigation,limit-post.php and all..It will show you fatal error...
Since I do not allow comments, the akismet plugin is not needed.
PHPexec - to allow php to execute inside post
Script enabler - to allow scripts inside of post
Light box effect of images
