No problem, I’m using version 4.9.2. I hope that helps!
Would you believe me @a2hostingrj if I told you I found that plugin about 10 minutes ago, installed it and it imported my blog perfectly! It was a real lifesaver (as I couldn’t for the life of me figure out what was going wrong!).
Thank you for the heads up, and it was only after I posted my question that I realised something may have been different because I was help-hosting.
Thank you again!
