WSS_Content log file which grown in GBs got deleted.
Now SharePoint sites showing 404 error. Using internal database SSEE. Any solution how can sites be running again.
You should have taken SQL backup before performing such changes.
To fix this you can try following
sqlcmd -S \\.\pipe\mssql$microsoft##ssee\sql\query -E
EXEC sp_detach_db [your_database_name]
EXEC sp_attach_db @dbname = N'WSS_Content', @filename1 = N'D:\SharePointDB\WSS_Content.mdf'
