Backie,
Thanks for getting back. I was getting the problem when I was cutting and pasting, words with apostrophes in them, from the backend of another website. I have deleted entries for those particular questions, input new questions and this time I type any word that uses an apostrophe. Does the trick.
I’m usin the WP survey and quiz tool which I find to be excellent. I just have one problem – I can’t seem to use single quotes in any of the questions. Is there some escape character that can be used to stop rubbish characters being put e.g. if I have a question with the word “aunt’s”, it will appear as “auntá” and the rest of the sentence is truncated. Thanks.
