Bug in the in the delete_associated_files function

    The wpcf7-redirect plugin (in the delete_associated_files function) retrieves the path to the file to delete from the post’s metadata (probably something like _uploaded_file_path or similar). If the CF7 form has an upload field that allows multiple files, that metadata is saved as an array of paths instead of a single string. The wpcf7-redirect code, however, doesn’t handle this case and passes the array directly to file_exists(), which crashes because it expects only a string.

    Steps to reproduce the bug:

    Create a form with a file_upload field that allows more than a file
    Add the action “Save lead” to the form
    Fill the form
    Put the filled form entry in the basket.
    Try to empty the basket
