I came across a journal on a random blog which argues over the below sentences.
I don't see any problems with the original sentence but some say it doesn't sound right... Can you please tell me if the original is wrong? And the reasons why??

Here's the original sentence: The use of English would never have spread around the world, were English a difficult language to learn.

This is the sentence which some say is correct: The use of English would never have spread around the world, had English been a difficult language to learn.

Thanks! :)
