I'm trying to install magento on localhost, but the installation does not go as high as 90%. I already changed the apache php.ini to
max_input_time = 1800
max_execution_time = 1800
memory_limit = 1024M
I restarted apache and setup, but then I had Error 503: Service Temporarily Unavailable, and I can only restart the installation if I replace the localhost / magento files with those of the original magento folder. Any idea what might be causing this?
