Hello,
Alex has just updated LINKSSQL from version 1.0 to 1.11. But when performing a search or adding a link the following error message comes:
Can't locate object method "root" via package "Links::Template" at
admin/Links/DB_Utils.pm line 208.
From the admin is everything working fine.
Please Help !!!

Sounds like something happened with the MySQL permissions file.

Ask Alex, since he just was in there, he'll probably know immediately what happened.
