Install error

Hi All,

Getting an error when I try to install a test version of opencart v4 on my local machine.
I'm using PHP Version 8.0.13 and I've also tried to use PHP 8.1.0 however despite all the extensions enabled I'm still getting mbstring related error.

The module is enabled and everything is loading fine and showing up in phpinfo() but I get this error
Fatal error: Uncaught Error: Call to undefined function Opencart\System\Helper\Utf8\mb_internal_encoding() in D:\Sites\VHost1\system\helper\utf8.php:3 Stack trace: #0 D:\Sites\VHost1\system\startup.php(63): require_once() #1 D:\Sites\VHost1\install\index.php(39): require_once('D:\\Sites\\VHost1...') #2 {main} thrown in D:\Sites\VHost1\system\helper\utf8.php on line 3

Could anyone advise please?

I'm using latest OpenCart version
PHP 8.0.13 and PHP 8.1.0 tested - same issue on both
As per the error, I'm running this on Windows within an WampServer build (can't see that being a problem tho?)

Thanks.

Make sure your PHP has the mbstring extension enabled.

Sorry for the delay in replying.
The module is enabled and is showing up in phpinfo()

In my case, opencart 4 installation problem ...\system\helper\utf8.php solved by editing php.ini on my localhost server:

in php.ini enable the following by removing ";":
mbstring.internal_encoding =
extension=curl
extension=gd
extension=mbstring
extension=openssl

good luck.
