Shortcode not working after move wordpress website files

On the page it shows as [vfb id=’1′]

But, when I view source code, it shows as [vfb id=’1′]

Look again at the code on the actual page – one mark is a right single quotation mark (8217) and the other character is called a ‘prime’ (8242).

Try removing the punctuation marks so it’s just [vfb id=1] (best to use ‘Text’ view in editor window for this).
