Error : Duplicate module "sql sql"

24 Dec 2023

      Hope this email finds you well.

I am facing this issue after i use this command " /usr/sbin/radiusd -C
-lstdout -xxx "
I got this error "Duplicate module "sql sql", in file
/etc/raddb/mods-enabled/sql.save:20 and file /etc/raddb/mods-enabled/sql:20
"
I even checked for duplicates in sql and sql.save files but I didn't find
any duplicates.

this is sql file in  mods-enable :

# If you want to have multiple SQL modules re-use the same

#  happens, it will open a new connection.  It will
