 * Hi all.
    Installed WP at [http://wp.crube.net](http://wp.crube.net) (php 4.3.2)
   and everything is working except for a warning error: Warning: ob_start(): output
   handler ‘ob_gzhandler’ cannot be used twice in /DISK3/WWW/crube.net/wp/b2-include/
   b2functions.php on line 640 Tried $use_gzipcompression = 0 in blog.header.php
   but the problem persists. Regards, Fallen
