Options not allowed here - 500 error
With some server configurations you may see an error message like one of the following:
/wp-content/cache/wp-rocket/.htaccess: Options not allowed here
Cannot serve directory... No matching DirectoryIndex and server-generated directory index forbidden by Options directive
For security purposes, WP Rocket adds an htaccess file and empty index file in the
cache/wp-rocket folder, to prevent anyone browsing the files.
The htaccess file contains the following:
<IfModule mod_autoindex.c> Options -Indexes </IfModule>
Therefore the errors above could happen because your host or server admin is disallowing Options -Indexes within an htaccess file.
This is not fixable by WP Rocket, but you should contact your web host or server admin and they can fix it for you.
options not allowed error can be triggered in relation to other directives. Check this article for more details.
