Magento 2.3 opening Installation leads to blank page

[henk_henk]

I've been trying to install Magento2 open source package on local server using MAMP.

PHP: 7.3.1

MySQL: 5.7.25

After opening http://localhost:8888/Magento I'm getting auto-re-directed to: http://localhost:8888/Magento/setup/

However the page is completely blank.

What can I do to complete installation?

Hello @henk_henk 

Try giving permission to the root folder of magento

sudo chmod -R 777 root folder of magento/

Hey @henk_henk 

Magento officially support PHP 7.2 version for magento 2.3.1.
https://devdocs.magento.com/guides/v2.3/install-gde/system-requirements.html

Try once with PHP 7.2 and give full permission to the folder when install.

sudo chmod -R 0777 YOUR_MAGENTO_FOLDER_PATH

I hope it will help you!

Thanks, but it didn't change anything. Still got the blank page. My magento2 folder is in MAMP / htdocs does that matter in any way? Also I run this on MAC.

Anyone has any solution?

Tried some troubleshooting and now I've got this error:
