It appears to be an Apache configuration problem on your server.
Apparently Apache is having trouble when a browser sends an 
If-Modified-Since header that is earlier than the Last-Modified
header generated by the PHP response.

Prior to 2.1.beta18, PmWiki would generate Last-Modified
headers only if $EnableIMSCaching was set true; 2.1.beta18 
changed this behavior to always generate a Last-Modified header
(but still  used $EnableIMSCaching to decide whether to act
on the If-Modified-Since header).

At any rate, this tells me that there are some problematic Apache
servers in the world, so PmWiki should go back to the pre-2.1.beta18
default of not generating Last-Modified headers unless explicitly
configured to do so.

Now fixed in 2.1.beta19, just released.  Hopefully that will resolve
the problems on your system (be sure to let me know if it doesn't).
