errors afrer upgrade?

[Doc90]

i'm testing the upgrade locally, with easy php.

my two config.php files are this (i cut comments for brevity)

/config.php

<?php
$config['baseurl'] = 'http://127.0.0.1:8888';
$config['baseurl_login'] = $config['baseurl'];
$config['admincpdir'] = 'admincp';
$config['cookie_prefix'] = 'bb';
$config['cookie_enabled'] = true;
$config['report_all_php_errors'] = false;
$config['no_template_notices'] = true;
$config['no_js_bundles'] = false;
$config['debug'] = false;
$config['core_path'] = realpath(dirname(__FILE__)) . '/core';
$config['baseurl_core'] = $config['baseurl']  .  '/core';

/core/include/config.php

<?php
$config['Database']['dbtype'] = 'mysql';
$config['Database']['dbname'] = 'test_forum';
$config['Database']['tableprefix'] = 'vb_';
$config['Database']['technicalemail'] = '[email protected]';
$config['MasterServer']['servername'] = 'localhost';
$config['MasterServer']['port'] = 3306;
$config['MasterServer']['username'] = 'root';
$config['MasterServer']['password'] = '';
$config['MasterServer']['usepconnect'] = 0;
$config['SlaveServer']['servername'] = '';
$config['SlaveServer']['port'] = 3306;
$config['SlaveServer']['username'] = '';
$config['SlaveServer']['password'] = '';
$config['SlaveServer']['usepconnect'] = 0;
$config['Misc']['admincpdir'] = 'admincp';
$config['Misc']['modcpdir'] = 'modcp';
$config['Misc']['cookieprefix'] = 'bb';
$config['Misc']['forumpath'] = '';
$config['SpecialUsers']['canviewadminlog'] = '1';
$config['SpecialUsers']['canpruneadminlog'] = '1';
$config['SpecialUsers']['canrunqueries'] = '';
$config['SpecialUsers']['undeletableusers'] = '';
$config['SpecialUsers']['superadministrators'] = '1';
$config['Cache']['class'][0] = 'vB_Cache_Db'; //regular cache
$config['Cache']['class'][1] = 'vB_Cache_Memory'; //fastest cache
$config['Cache']['class'][2] = 'vB_Cache_Db'; //largest cache and longest life.
$config['Mysqli']['ini_file'] = '';
$config['Misc']['maxwidth'] = 2592;
$config['Misc']['maxheight'] = 1944;

(there's no ?> right?)

(sometimes) the upgrade process ends with no errors, and when i try to navigate forums i got only messages like:

on forums/categories/threads

An internal error has occurred and the widget cannot be displayed.

on userprofiles

That action could not be completed. Please try again, and if this occurs again please contact the system administrator and tell them how you got this message.

css are messed up and in forum options there's

http://127.0.0.1:8888/core

as forum url

Settings look correct. Does Easy PHP support mod_rewrite via Apache? This is required to run vBulletin 5. It appears your rewrites aren't working properly.

Might try using XAMP instead of Easy PHP. Or check out - http://www.easyphp.org/faq.php#0
