Add FULLTEXT to that column

ALTER TABLE table ADD FULLTEXT index_name(column1);
enter your table and column names and try this

always make a backup before doing any work ;)

Verify the fulltext indexes exist in phpmyadmin on the post & thread tables.

Remove the fulltext index in phpmyadmin
Add the fulltext index manually in phpmyadmin or vb's admincp
