Error in installing magento 1.9

Question

I am trying to install magento 1.9.3.4. But there are some problems in magento installation wizard. I am getting following errors in browser console.

Answer 1

I think your magento folder permission is wrong fire below commands in your magento root

chmod -R 644 ./*

find . -type d -exec chmod 755 {} \;

find . -type f -exec chmod 644 {} \;

chmod 550 ./mage

Fire above for command one by one any your problem would solve
