If you're trying to submit a review on a Host or WWOOFer profile and the button is disabled, it's likely because that member has already posted a review on your profile more than 14 days ago and the review period is over.
Other possible reasons why the review button is disabled:
- You have never purchased a WWOOF membership
- You have already reviewed this member
- You are trying to post to a host profile as a host, or to a WWOOFer profile as a WWOOFer
