--- 1. Query

SELECT name, log_reuse_wait_desc FROM sys.databases

--- check if MyDatabaseName says

--- log_reuse_wait_desc = Replication

--- 2. Force removal of the replication.

EXEC sp_removedbreplication MyDatabaseName

--- 3. Check

SELECT name, log_reuse_wait_desc FROM sys.databases

--- check if MyDatabaseName says

--- log_reuse_wait_desc = Nothing

--- 4. Force your DB to Simple Recovery:

ALTER DATABASE MyDatabaseName SET RECOVERY SIMPLE

--- 5. Run db shrink command

backup log MyDatabaseName with truncate_only

dbcc shrinkfile(MyDatabaseNameLog)

--- Perfect

--- thanks again 🙂
