Apache Error 500 (Internal Server Error)

When loading DokuWiki, I'm getting an Error 500 (Internal Server Error), what should I do?

This can happen if the .htaccess files in your DokuWiki directory use settings or trigger actions which are not supported by your Apache server config. If you're not running the server yourself, but are registered with a webhost, you can either ask your webhost to enable the options in question, or just comment them out in the htaccess files.

The options which are known to cause an Error 500 are:

Options -Indexes

as well as all settings related to Apache's mod_rewrite option to pretty-print URLs. The latter are disabled by default.

It my also occure when setting very permissive file permissions (777) and your hoster added some security checks to avoid this. Try to lower permissions.

Another problem can occur if you're using .htaccess files using UTF-8 codification with Byte-Order Mark (BOM). Reencode your .htaccess files properly without BOM to solve this.

Some people reported a 500 error when creating new users or chaniging passwords on certain hosters. Try to change the passcrypt option from smd5 to md5.
