I have installed Magento 2.3.0 from site ground, when clicking the link to my website i get this:
Parse error: syntax error, unexpected '?', expecting variable (T_VARIABLE) in /home/motiveat/public_html/vendor/magento/framework/Filesystem/Directory/Write.php on line 35
what do i do?, what have i done wrong? i am not tech savvy and just want to build my website
thanks
