I found a bug/error while trying to change the link status from "Yes" to "No" for Validated.

------ Bug ------
A fatal error has occured:

GT::SQL::Table (9219): Unknown method '_delete_index' called at /home/user/public_html/cgi-bin/admin/Links/Link.pm line 283.
Please enable debugging in setup for more details.

Can anyone tell, how to solve this problem.
