Pay to review?

Hi

Just had a message from a confused lister, one of their customers tried to add a review to their business listing, but were told they have to pay?! I can’t recreate this, does anyone know what she means or how to stop this? Certainly don’t want to charge people to leave a review!

I’m trying to add test reviews right now to a listing but every time I try I either get the following error;

Warning: Missing argument 2 for geodir_reviewrating_wrap_comment_text() in /home/rrokngem/public_html/thehouseofdog.co.uk/wp-content/plugins/geodir_review_rating_manager/geodir_reviewrating_template_functions.php on line 20

Warning: Cannot modify header information – headers already sent by (output started at /home/rrokngem/public_html/thehouseofdog.co.uk/wp-content/plugins/geodir_review_rating_manager/geodir_reviewrating_template_functions.php:20) in /home/rrokngem/public_html/thehouseofdog.co.uk/wp-includes/pluggable.php on line 1121

or a 500 server error.

When I get all the code, the reviews come through for to be checked, but not when I get the 500 error.

I think I have some issues going on here. Please can someone take a look/advise?

Thanks

Sally
