Invision Powerboard 1.2 and 1.3 are still used by many people because they’re free, where the newest versions are not. However, the coding for them isn’t 100% compatible with the latest versions of PHP and MySQL. Many web hosting companies are moving to PHP5 and MySQL5, and this will break the default installation of IPB. Here is a collection of the changes you’ll need to make to your files so that IPB 1.2 or 1.3 will work with PHP5 & MySQL 4.1 or greater.

If your forum is experiencing any of these issues, the rest of this article may fix your problem. Make sure you back up your files and database before making any changes, just in case.

Symptoms:

Blank ‘Profile’ page
Blank ‘My Controls’ page
MySQL errors when reporting post
MySQL errors on ‘The Moderating Team’ page

Files affected:

sources/misc/contact_member.php
sources/Profile.php
sources/Usercp.php
sources/misc/stats.php

Step 1:
Open sources/Usercp.php

Find:

var $parser;

Change To:

//var $parser;

Save and upload sources/Usercp.php

Step 2:
Open sources/Profile.php

Find:
var $parser;

Change To:
//var $parser;

Save and upload sources/Profile.php

Step 3:
Open sources/misc/contact_member.php
Find:

var $email = “”;
var $forum = “”;
var $email = “”;

Change To:

//var $email = “”;
var $forum = “”;
var $email = “”;

Find:

$DB->query(”SELECT m.name, m.email, mod.member_id FROM gallerymoderators mod, gallerymembers m WHERE mod.forum_id=’$fid’ and mod.member_id=m.id”);

Change To:

$DB->query(”SELECT m.name, m.email, moder.member_id FROM gallerymoderators moder, gallerymembers m WHERE moder.forum_id=’$fid’ and moder.member_id=m.id”);

Save and upload sources/misc/contact_member.php

Step 4:
Open sources/misc/stats.php
Find:

//——————————————–
// Do we have any moderators? NORMAL MODS 1st
//——————————————–

$DB->query(”SELECT m2.id, m2.name, m2.email, m2.hide_email, m2.location, m2.aim_name, m2.icq_number,
f.id as forum_id, f.read_perms, f.name as forum_name, c.state
FROM gallerymoderators mod
LEFT JOIN galleryforums f ON(f.id=mod.forum_id)
LEFT JOIN gallerycategories c ON(c.id=f.category AND c.state != 0)
LEFT JOIN gallerymembers m2 ON (mod.member_id=m2.id)
“);

Change To:

//——————————————–
// Do we have any moderators? NORMAL MODS 1st
//——————————————–

$DB->query(”SELECT m2.id, m2.name, m2.email, m2.hide_email, m2.location, m2.aim_name, m2.icq_number,
f.id as forum_id, f.read_perms, f.name as forum_name, c.state
FROM gallerymoderators moder
LEFT JOIN galleryforums f ON(f.id=moder.forum_id)
LEFT JOIN gallerycategories c ON(c.id=f.category AND c.state != 0)
LEFT JOIN gallerymembers m2 ON (moder.member_id=m2.id)
“);

Find: (this edit isn’t in 1.2, so you should be able to skip this step if that’s your version)

//——————————————–
// Do we have any moderators? GROUP MODS 1st
//——————————————–

$DB->query(”SELECT m.id, m.name, m.email, m.hide_email, m.location, m.aim_name, m.icq_number,
f.id as forum_id, f.read_perms, f.name as forum_name, c.state
FROM gallerymoderators mod
LEFT JOIN galleryforums f ON(f.id=mod.forum_id)
LEFT JOIN gallerycategories c ON(c.id=f.category AND c.state != 0)
LEFT JOIN gallerymembers m ON ((mod.is_group=1 and mod.group_id=m.mgroup))
“);

Change To:

//——————————————–
// Do we have any moderators? GROUP MODS 1st
//——————————————–

$DB->query(”SELECT m.id, m.name, m.email, m.hide_email, m.location, m.aim_name, m.icq_number,
f.id as forum_id, f.read_perms, f.name as forum_name, c.state
FROM gallerymoderators moder
LEFT JOIN galleryforums f ON(f.id=moder.forum_id)
LEFT JOIN gallerycategories c ON(c.id=f.category AND c.state != 0)
LEFT JOIN gallerymembers m ON ((moder.is_group=1 and moder.group_id=m.mgroup))
“);

Save and upload sources/misc/stats.php

Step 5:
Add the following code to the top of index.php and admin.php:

//– mod_php5 begin
$HTTP_SERVER_VARS = isset($_SERVER)?$_SERVER:array();
$HTTP_GET_VARS = isset($_GET)?$_GET:array();
$HTTP_POST_VARS = isset($_POST)?$_POST:array();
$HTTP_POST_FILES = isset($_FILES)?$_FILES:array();
$HTTP_COOKIE_VARS = isset($_COOKIE)?$_COOKIE:array();
$HTTP_ENV_VARS = isset($_ENV)?$_ENV:array();
$HTTP_SESSION_VARS = isset($_SESSION)?$_SESSION:array();
//– mod_php5 end
