• Had to troubleshoot this error for a client, “Bad end offset:”

    The solution to get around the LiteSpeed issue was to add this to .htaccess:

    # Force LiteSpeed to respect byte-range chunked loading for PDFs
    <IfModule mod_headers.c>
    <FilesMatch “.(pdf)$”>
    Header set Accept-Ranges bytes
    Header set Cache-Control “no-cache, no-store, must-revalidate”
    Header set Pragma “no-cache”
    Header set Expires 0
    </FilesMatch>
    </IfModule>
