Silverstripe cannot write manifest file check permissions of

This indicates that a file associated with a form submission does not have the recommended permissions applied to it. A caution symbol is added to the form submission icon because it has a higher risk of being publicly accessible if it is published. To learn more about the usage of these icons in form submissions refer to Form submissions, File Upload Field.

If you are deploying your site to a server configuration that makes use of static caching, it's essential that you ensure any page or dataobject cached adequately publishes any linked assets.

This is due to the fact that static caching will bypass any PHP request, which would otherwise be necessary to whitelist protected files for these users. This is especially important when dealing with draft content, as frontend caches should not attempt to cache protected content being served to authenticated users.

This can be achieved by configuring your cache correctly to skip Pragma: no-cache headers and the bypassStaticCache cookie. In most cases, developers can interact with File and Image objects without worrying about how Silverstripe CMS resolves file names or responds to requests. Some advanced use cases may occasionally require developers to adjust the HTTP response for file requests.

Most of the routing logic for serving Files is controlled via the AssetStore interface. In order to better ensure these files are protected, it's recommended to move this outside of the web root altogether.

In certain situations, it's necessary to customise HTTP headers required either by intermediary caching services, or by the client, or upstream caches. You can customise this with the below config:. When a user tries to access a file that exists, but for which they do not have access, Silverstripe CMS will return a " Not found" response rather than a " Denied" to avoid revealing the existence of the file.

You can customise the response codes for various types of requests via configuration flags on FlysystemAssetStore. To achieve this create an Extension and implement the updateResponse method. By default, the default extension AssetControlExtension will control the disposal of assets attached to objects when those objects are archived or replaced. For example, unpublished versioned objects will automatically have their attached assets moved to the protected store.

The archive of draft or or deletion of unversioned objects will have those assets permanently deleted along with all variants. Note that regardless of this setting, the database record will still be archived in the version history for all Versioned DataObjects. In some cases, it may be preferable to have any assets retained for archived versioned dataobjects, instead of deleting them.

This uses more disk storage, but will allow the full recovery of archived records and files. Note that this feature only works with dataobjects with the Versioned extension. While default configuration is in place to avoid the webserver serving these files, we recommend moving them out of the webroot altogether - see Server Requirements: Secure Assets.

If the default server configuration is not appropriate for your specific environment, then you can further customise the. Each of these files will be regenerated on? You will need to ensure that your core apache configuration has the necessary AllowOverride settings to support the local.

Although assets have a handler which routes to a PHP handler,. When securing your server you should ensure that you protect against both files that can be uploaded as executable on the server, as well as protect against accidental upload of.

Configuring via IIS requires the Rewrite extension to be installed and configured properly. Any rules declared for the assets folder should be able to dynamically serve up existing files, while ensuring non-existent files are processed via the Framework. You will need to make sure that the allowOverride property of your root web.

If using a server configuration which must be configured outside of the web or asset root, you will need to make sure you manually configure these rules.
