If you're performing explicit locks using LOCK TABLES, the manual
states you must acquire appropriate locks for *all* tables you're

If you're only using site and siteq is a single query you don't need
to use LOCK TABLES because the server will acquire the necessary locks
automatically.  If this is what you're doing and you're getting the
error message, I don't know what's going on.
