The first time i installed october cms using the wizard installation the setup was done perfectly without any issues on my mac. But after upgrading my operating system on mac to Mojave 10.14.14 and when i tried to access the page at the following url http://localhost/install-master/ i was getting some php errors. So i deleted all the files pertaining to October cms and tried reinstalling them via the wizard installation process, but when i tried access the file install.php at the following url

http://localhost/install-master/install.php

Nothing seems to happen, it just shows the default index.php page, please help how can i reinstall october cms using the wizard?
