Feed on Feeds & PHP 4.3.2: Workaround
You can work around the problem in PHP 4.3.2 by adding this line to the end of your config.php, just before the closing ?>:
define('MAGPIE_USE_GZIP', false);
Something seems to have changed with PHP’s gzinflate function. So the workaround is to turn GZip encoding off completely until we figure out what is going on. FoF will work fine with GZip turned off, but since the RSS files fetched will not be compressed, it will use more bandwidth.
