Seems to work fine for me on 1.18 dev wiki

On the Upgrade existing installation step, what do you get?

The important LQT stuff is something like the below:

Creating thread table...ok
...user_message_state table already exists.
...thread_history table already exists.
...thread_pending_relationship table already exists.
...thread_reaction table already exists.
...have thread_article_namespace field in thread table.
...have thread_article_title field in thread table.
...have thread_ancestor field in thread table.
...have thread_parent field in thread table.
...have thread_modified field in thread table.
...have thread_created field in thread table.
...have thread_editedness field in thread table.
...have thread_subject field in thread table.
...have thread_author_id field in thread table.
...have thread_author_name field in thread table.
...have thread_sortkey field in thread table.
...have thread_replies field in thread table.
...have thread_article_id field in thread table.
...have thread_signature field in thread table.
...have ums_conversation field in user_message_state table.
...thread_summary_page key already set on thread table.
Purging caches...done.
Checking site_stats row...done.

Alright, found the problem and it was rather simple:

I was following the instructions described at http://svn.wikimedia.org/viewvc/mediawiki/trunk/extensions/LiquidThreads/README?view=markup interpreting that the steps were:

1. Download and unpack extension in server folder.
2. Run the updater.
3. Enable extension in LocalSettings.php

However the correct steps when using the web updater are:

1. Download & unpack.
2. Enable extension.
3. Run updater.

Then it works.

The instructions at http://www.mediawiki.org/wiki/Extension:LiquidThreads#Installation are correct. The README file could be updated using them? I went for the README assuming that the instructions there would be more recent, since some of the info at the wiki page is still referring to the old "beta".

Thank you and sorry for the noise.
