Mythweb shows only a blank page

[KimKulak]

Binary package hint: mythtv

Ubuntu 8.10

Whenever I try to access mythweb all I get is a blank page. (Mythweb version 0.21.0+fixes18722-0ubuntu1)

I do get this error message in /var/log/apache2/error.log:
<br />
<b>Fatal error</b>: Unknown: Cannot use both zlib.output_compression and output_handler together!! in <b>Unknown</b> on line <b>0</b><br />

I first noticed the problem after this update (/var/log/apt/term.log). It worked great the day before the update:

I checked these configuration files:

Couldn't find zlib.output_compression turned on anywhere.

I filed this bug under mythweb because I have phpmyadmin on the same server and it is displaying properly.

That's as far as I can go trying to find the source of this problem. Is there any more information you could want or anything that I should try?
