Answer 1

This is most likely due to your file permissions not set properly and this is also stated as the reason in your 500 error page.

You will firstly need to know if your server is running suPHP / suEXEC. If it is, make sure all files are set to 644 and all directories to 755.

Changing the permissions should usually be enough to resolve the issue.

You may need to take note though because if you run the Magento in-built backup feature, it may reset the file permission back to those which includes 666 and 777 which may cause the error again and you will have to reset it back to 644 and 755.
