Hi, the above way does work but if (like me) you have several posts/pages with reviews it will take a long time to manually go in and insert the code.
I played around with wp-customer-reviews.php and I am not a developer at all and I got it working, I am so happy! I need to test on chrome to make sure it works as IE and FF are ok.
What I did….download WordPress Access Control pluggin.
Edit wp-customer-reviews.php and around line 1056 I inserted a [member] and on line 1075 (after the </tbody> I inserted the closing [/member]
Then just after the [/member] I added [nonmember] Please login to post a review[/nonmember] and it worked…:)
Check my website.
Being a non techy I am realy happy as I was going to pay for this!
What I would like now is for an avatar on the reviews!
