Similar Entries 2 (6.2) - http://drupal.org/project/similar - doesn't work. But version 1 works like a charm. Version 2 spits up an error on array_filter. Looking at the code, my guess is it's related to some new Views plugin code in version 2.

Related Block - http://drupal.org/project/related_block - would have been cool too. It's much like Similar Entries. Unfortunately, the search algorithm is way too narrow. At first, I couldn't tell if the module was even working. Then by weening the search terms down to 1 (which means it figures out a single relevant term and then searches for only that) I saw some results, but not on many nodes still.

Relevant Content - http://drupal.org/project/relevant_content - is nice in theory. Currently, it's broken. It's in the middle of a rewrite, but it's looking more and more unlikely that it will ever get rewritten.

Related links - http://drupal.org/project/relatedlinks - is not what it seems. It just finds any referenced links in the content and groups them together. Nothing external.

Other modules are term (taxonomy) based. But ideally, you don't need to specify all the relevant terms, and you don't need to explicitly say that two terms are related. There should be a more intelligent way.

Fatal error: Call to undefined function: block_list()

On a Drupal 6 site where I had copied over a database to be used with a freshly checked out tree, I suddenly got this fatal error which stopped any page from loading:

Fatal error: Call to undefined function: block_list() in .../theme.inc on line 935

I'm not sure how it happens. And even after it happens, it's not always immediately a problem. It can be a problem that manifests itself when migrating or copying a database from one site to another. And for some reason, the exact same database worked on another site.

In my case, the problem was the filenames for some core modules and themes and you can see if that's your problem by running this query:

SELECT count(*) FROM system WHERE filename LIKE '%modules/modules%' OR filename LIKE '%themes/themes%';

If that returns anything (like a filename like 'modules/modules/block/block.module') then you have a problem which you can fix by running:

UPDATE system SET filename = replace(filename, 'themes/themes', 'themes');
UPDATE system SET filename = replace(filename, 'modules/modules', 'modules');
