Not really a bug but: I had a problem with indexing in mysql scheme. I had LinksSQL running in InnoDB and did not know that
ADD FULLTEXT $ft_name ( $cols )
from /cgi-bin/admin/GT/SQL/Search/MYSQL/Indexer.pm won´t work with InnoDB.
Changing to MYIsam solved this problem so far.
I dont´t know if I forced this problem but maybe it is possible to add an error message for future Versions.
It might help other Users.
