After upgrading to php 7.0.4, laravel began to swear that there is no function

Illuminate \ Foundation \ Bootstrap \ mb_internal_encoding ()

Uncaught Error: Call to undefined function Illuminate\\Foundation\\Bootstrap\\mb_internal_encoding() in ./vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php:43 Stack trace: #0 /var/www/safari/vendor/laravel/framework/src/Illuminate/Foundation/Application.php(183): Illuminate\\Foundation\\Bootstrap\\LoadConfiguration->bootstrap(Object(Illuminate\\Foundation\\Application)) #1 /var/www/safari/vendor/laravel/framework/src/Illuminate/Foundation/Http/Kernel.php(199): Illuminate\\Foundation\\Application->bootstrapWith(Array) #2 /var/www/safari/vendor/laravel/framework/src/Illuminate/Foundation/Http/Kernel.php(110): Illuminate\\Foundation\\Http\\Kernel->bootstrap() #3 /var/www/safari/vendor/laravel/framework/src/Illuminate/Foundation/Http/Kernel.php(84): Illuminate\\Foundation\\Http\\Kernel->sendRequestThroughRouter(Object(Illuminate\\Http\\Request)) #4 /var/www/safari/public/index.php(52): Illuminate\\Foundation\\Http\\Kernel->handle(Object(Illuminate\\Http\\Request)) #5 {main} thrown in /var/www/safari/vendor/laravel/framework/src/Illuminate/Foundation/Bootstrap/LoadConfiguration.php on line 43 php -v PHP 7.0.4-7+deb.sury.org~trusty+2 (cli) php -m | grep mb mbstring php -r 'echo mb_internal_encoding("UTF-8").PHP_EOL;' 1

    • Thank you, but the error turned out to be different. After installing php-mbstring, I just didn’t restart Apache. - Alexey Dorohov
    • It was there that they wrote about) - Vasily Barbashev
