Thanks for the detailed report of your installation, unfortunately I see no 
obvious problem there. 

There are some changes to the PageStore class since version 2.2.31: there is a 
function that converts between different character encodings. I've recently 
fixed a similar issue with blank pages.

However for your installation which had the default ISO-8859-1 encoding, 
nothing have changed, the recoding function is not used.

Have you any problems with some other pages from the default installation, for 
example blank pages in the PmWiki/ or Site/ groups? These pages come with the 
UTF-8 encoding and are converted to yours on the fly.

If you add the following line to config.php, do you still have blank pages?

  $PageRecodeFunction = 'IsEnabled';

(This line will completely bypass the PageStore->recode function.)

Can you test some previous PmWiki versions 2.2.30 to 2.2.35 on the same server 
and report?
