The Issue¶

"Hash has to be non-empty string."
Entries in sys_file table point to non-existing files on the server

Solution¶

Ensure that the files contained in your fileadmin/ tree are consistent with your sys_file database relations.

You may either be missing referenced files in fileadmin/, or sys_file lists outdated entries.

The CLI command typo3 cleanup:missingfiles may help synchronizing your database to the current fileadmin/ structure.
