Description:
It looks like the export function doesn't create a right encoding header, so mod_gzip doesn't recognise it as already gziped and gzip it again. The result is a non readable text, because browsers only unzip once.
The produced encoding header looks like this:
Content-Encoding: , gzip
At the moment I only found a workaround by commenting some parts in includes/GlobalFunctions.php:
function wfResetOutputBuffers( $resetGzipEncoding=true ) {
while( $status = ob_get_status() ) {
if( $status['type'] == 0 /* PHP_OUTPUT_HANDLER_INTERNAL */ ) {
echo 'status 0';
// Probably from zlib.output_compression or other
// PHP-internal setting which can't be removed.
//
// Give up, and hope the result doesn't break
// output behavior.
break;
}/* Commented because of encoding errors
if( !ob_end_clean() ) {
// Could not remove output buffer handler; abort now
// to avoid getting in some kind of infinite loop.
break;
}
if( $resetGzipEncoding ) {
if( $status['name'] == 'ob_gzhandler' ) {
// Reset the 'Content-Encoding' field set by this handler
// so we can start fresh.
header( 'Content-Encoding:' );
}
}*/
}
