 * Hi, how do “enable missing extension(s) or remove Comet Cache from WordPress.”
   As I get this message when I activated the plugin
 * PHP Extension(s) Missing
    Comet Cache is not active. It depends on PHP extension(
   s): mbstring. An action is necessary. Please contact your hosting company for
   assistance. To remove this message, enable missing extension(s) or remove Comet
   Cache from WordPress.

 * [@kbooshco](https://wordpress.org/support/users/kbooshco/) Comet Cache requires
   the PHP `mbstring` extension. Your web hosting company needs to enable that PHP
   extension, so I recommend contacting their support department.
 * If you want to uninstall Comet Cache, you can do that by visiting the Plugins
   section of your WordPress Dashboard and clicking “Deactivate” underneath the 
   Comet Cache plugin. Then once it’s deactivated, you can “Delete” it.
