Hi!
I had the same issue with wordpress v3.3.1 and link-library v5.4.8, no links were shown, using v5.4.6 did not make any difference either.
When I manually ran the database query the plugin does to find links, it turned out that there was the “links_extrainfo” table missing from database.
I could not make that table appear to database, just commented out link-library.php:561 (revision 523547) and the plugin seemes to be functional now ??
Hope, that helps Yannick to find the problem.
