 * I am using WordPress2.8.4.
 * I am using a rental server to host my WordPress website.
    PHP on my server is
   changeable from 4 to 5 or from 5 to 4 by one click of a button on the control
   panel.
 * Recently, I changed php on my server from 4 to5. Then my WordPress become unstable.
 * The first time I changed from php 4 to php5, my web site got blank though the
   control panel was fine. Therefore, I erased database and files from server. Then,
   I tried installing WordPress2.8.4 again on PHP5, but I was not able to login 
   to WordPress after the install (though I was able to install the WordPress). 
   Because, after entering userID (admin) and password and push Login button, the
   website got blank.
 * I searched on internet and I found that comment out Line 337of “wordpress/wp-
   includes/canonical.php” is a solution.
    Line 337 : add_action(’template_redirect’,’
   redirect_canonical’);
 * After erasing the line above, my WordPress behave right on php5 only “after” 
   installing it.
    But I still can not install WordPress on PHP5 because of the 
   problem I mentioned (Because, after entering userID (admin) and password and 
   push Login button, the website got blank.).
 * Currently, When I install WordPress, I have to use PHP4. Then, after installing
   it, I change PHP4 to PHP5 by clicking the button on the control panel of my server.
 * Does anybody know which code I should change to install WordPress2.8.4 with PHP5?
   
   For some reason, I have to use WordPress2.8.4 little longer without upgrading
   it.
 * By the way, I tried with WordPress2.9.1. But the result was the same. On my server,
   I failed to install WordPress2.9.1. on PHP5.
 * OS: Linux
    Web server: Apache2 php4 or 5 MySQL4.1
