What does the Options -Indexes parameter in .htaccess do?

Question

htaccess

What is the Options -Indexes parameter in .htaccess responsible for and why can it cause a 500 error?

Answer 1

Options -Indexes
shows a list of files in the directory (or a 403 access denied error) if there is no default file (index.html, index.php).
The 500 error is probably because it conflicts with other rules or settings, such as Options -Multiviews. Options may vary.

Answer 2

Open the apache error log and see why there is such a problem
