links on homepage just produce plain page

[Bodo Teichmann]

Hi,
Problem: After installing phpwiki 1.3.4.,  i could see the startpage index.php, but when i click on a link i got just a plain white page.

Solution: i found that the link format
"http://myhostx.com/phpwiki/index.php/WikiWikiWeb"
does not work. So I commented in this line in index.php:

if (!defined('USE_PATH_INFO')) define('USE_PATH_INFO', false);

now the links look instead like this:

http://myhostx.com/phpwiki/index.php?pagename=WikiWikiWeb

and phpwiki now works as expected!

Now my question:
How can i get

if (!defined('USE_PATH_INFO')) define('USE_PATH_INFO', true);

to run ?
