Not showing correct output

Yeah, 'show source' shows all that. Are you sure you got everything else?

No whitespace before or after php code.
Controller in the right place and filename starts with a lower case.
While we're at it, your constructor name should match the class (ucfirst)

If nothing helps, try renaming the welcome controller and move the blog stuff in there.
