I installed this plugin on my site and noticed that the Site Title was being duplicated or "doubled up." For example, the title of the site is CaffeineAura and the resulting title was CaffeineAuraCaffeineAura.
I was able to fix this by editing the plugin. If you're having this issue, look for the function "basic_seo_title" and remove any instances of the $name variable within the function.
Otherwise, the plugin works great!
