Personally I just uploaded a site of mine made in Laravel 5.2 with pho 5.6 locally. I uploaded to a shared hosting in Locaweb that I have. I configured PHP 5.6 correctly and uploaded the site to this giving me the following error message.
Fatal error: Call to undefined function Symfony \ Polyfill \ Mbstring \ iconv_strpos () in /home/storage/b/71/41/supra/public_html/vendor/symfony/polyfill-mbstring/Mbstring.php on line 351
This is the first site I upload in version 5.2 of Laravel. In version 5.1 I never had any problems. See if you can help me. Thank you very much
