 * Hi.
 * I’m using this awesome calendar plugin to manage events at my website but have
   a problem using PHP version 7. It’s a virtual machine (testing) with Ubuntu 16.04.
   Installed php7.0-mbstring an restarded php7 and nginx services.
    I can see the
   module if I do a ‘php -m’ at the terminal prompt but every time I access to the
   configuration of the ai1ec plugin it warns me about mbstring missing.
 * What should I do? Thanks

 * Hi ftorresibez!
 * Do you use php-fpm? If yes, did you restart php-fpm?

 * Hi ftorresibesz,
    dear Calvin.
 * I encountered the same problem.
    After upgrading from php 5 to php 7, the default
   ubuntu install did not contain the mbstring extension anymore. So that was when
   the plugin started displaying the corresponding error message.
 * I thought fixing the issue should be easy enough:
 * >  aptitude install php-mbstring
   >  phpenmod mbstring service apache2 reload
 * and indeed this installed and enabled the mbstring extension.
    Nevertheless the
   error message was still there.
 * I could of course manually hide it with the accompanying button,
    but I don’t
   want to do that for every blog on this server. Furthermore when the mbstring 
   extension gets deactivated again, the message would remain hidden.
 * Unfortunately the only thing I could discern from your source code,
    was that
   the message is generated in `lib/environment/check.php` and is related to the`
   ai1ec_mbstring_notification` option.
 * Please let the message disappear automatically, in case you detect the mbstring
   extension.
