I'd like to avoid others this headick of searching hours for a hard problem to guess...
I had a problem: many links on Tikiwiki 4.1 (and also 4.2) wouldn't show up correctly, the "page" variable wouldn't add up to the link. So i would somehow could not do proper actions on the Tikiwiki pages (the page bar and the admin).
So after searching, it is a issue related to the http_build_query function, during the parsing with SMARTY.
I was trying to install on PHP 5.1.1 on a Windows XAMPP Installation.
The problem was that my version of http_build_query was not working properly. It would accept only 2 parameters of the 3. Strange?
So i fixed it by modifying the file lib/smarty_tiki/function_query.php
Around line 95, change to:
if (eregi("Win32", $_SERVER['SERVER_SIGNATURE'])) $ret = http_build_query($query); else $ret = http_build_query($query, '', $sep);
So make sure http_build_query is working properly!
