Hi, Still i was getting this error while installing 9.0.2-2.1 , i am using MAMP (mac os),I am encountering an HTTP 500 error in the 'Install themes' and 'Post-installation scripts' sections. Sometimes, the error occurs earlier in the 'Create default shop and languages' section. Could you please help me resolve this issue?

I was getting 500 error when there where problems with folder/file permissions. Try to make your mane folder (where you're installing presta, like /html/shop with permissions 777, check that mode_rewrite is enabled, check that apache conf file has AllowOveride All (if this setting is not on, later you'll get error when accessing Admin panel) -> using terminal or file manager open apache2.conf file for edit (/etc/apache2/apache2.conf)

In that config file locate "<Directory /var/www/>" directive and look for "AllowOverride None" line and change to "AllowOverride All"

Restart apache server

Delete previous presta9 install and reinstall it.

It worked for me and I can log into Back Office (admin account)

Goodluck

even i tried this ,still remain same...
