Thread:Support/failing to install Translate on my mediawiki instance: table not found

I am trying to add Translate extension to my instance of mediawiki @ http://rusefi.com but I am experiencing a 'table not found' error, I hope it's the right place to ask for help?

I believe that I have followed the http://www.mediawiki.org/wiki/Extension:Translate#Installation instruction precisely - I have uploaded the new folder to my server and I have added one line into my LocalSettings.php - I believe that's all the Installation section requires?

Unfortunately I am getting an error: Query: SELECT tmi_value FROM `wiki_translate_messageindex` WHERE tmi_key = '0:main_Page' LIMIT 1 Function: DatabaseMessageIndex::get Error: 1146 Table 'db515168816.wiki_translate_messageindex' doesn't exist (db515168816.db.1and1.com) Backtrace: 0 /homepages/5/d451478433/htdocs/wiki/includes/db/Database.php(1039): DatabaseBase->reportQueryError('Table 'db515168...', 1146, 'SELECT tmi_val...', 'DatabaseMessage...', false) 1 /homepages/5/d451478433/htdocs/wiki/includes/db/Database.php(1496): DatabaseBase->query('SELECT tmi_val...', 'DatabaseMessage...') That's with some debugging options in my config.

What am I missing here? is it required to run any sort of 'maintenance' scripts in order to install the extension? Where can I read about it? Is it absolutely required to have shell access in order to Install Tranlsate? I know that In addition, shell access is required to run maintenance scripts. but it is a bit vague if installation itself is a maintenance task :)

I have MediaWiki 1.22.2, PHP 5.4.25 (cgi-fcgi), MySQL 5.1.73-log
