Заменяет ссылку профиля site.ru/user/test/ на site.ru/journal/test/

Для начала редактируем ЧПУ:

1. Открываем .htaccess

Найти:
# вывод для отдельного юзера

RewriteRule ^user/([^/]*)/rss.xml$ engine/rss.php?subaction=allnews&user=$1 [L]
RewriteRule ^user/([^/]*)(/?)+$ index.php?subaction=userinfo&user=$1 [L]
RewriteRule ^user/([^/]*)/page/([0-9]+)(/?)+$ index.php?subaction=userinfo&user=$1&cstart=$2 [L]
RewriteRule ^user/([^/]*)/news(/?)+$ index.php?subaction=allnews&user=$1 [L]
RewriteRule ^user/([^/]*)/news/page/([0-9]+)(/?)+$ index.php?subaction=allnews&user=$1&cstart=$2 [L]
RewriteRule ^user/([^/]*)/news/rss.xml(/?)+$ engine/rss.php?subaction=allnews&user=$1 [L]

Заменить на (в вашем случае):

# вывод для отдельного юзера
RewriteRule ^journal/([^/]*)/rss.xml$ engine/rss.php?subaction=allnews&user=$1 [L]
RewriteRule ^journal/([^/]*)(/?)+$ index.php?subaction=userinfo&user=$1 [L]
RewriteRule ^journal/([^/]*)/page/([0-9]+)(/?)+$ index.php?subaction=userinfo&user=$1&cstart=$2 [L]
RewriteRule ^journal/([^/]*)/news(/?)+$ index.php?subaction=allnews&user=$1 [L]
RewriteRule ^journal/([^/]*)/news/page/([0-9]+)(/?)+$ index.php?subaction=allnews&user=$1&cstart=$2 [L]
RewriteRule ^journal/([^/]*)/news/rss.xml(/?)+$ engine/rss.php?subaction=allnews&user=$1 [L]
