Hi Matt, > Ok I found MOD_GZIP 2.0.26a > ... > Any ideas? Don't use this one. The Apache API has changed a lot from 2.0.26 to 2.0.40. Look out for mod_gzip 2.0.43, if any - if you find one this means that someone has adapted it to the current Apache 2.0 release. But don't expect your mod_gzip 1.3 configuration to work.
