I've implemented Subscribe2 on my site for users to follow my updates. The process uses a 2 stage subscription. 1. The user submits their email address. 2. They receive an email with a link that they need to follow to confirm their subscription. When they follow the confirmation link, all the titles on the page are replaced with "Subscription Confirmed". I raised this with the plugin author and received the following response:
That will be due to a conflict with your theme. I've seen this before. It is caused when the collection of the post titles and links is done using a function that WordPress say should only be used within the_loop(). The header, footer and sidebar should not use these functions.
You can test it out at http://southwestgarden.org. What can be done about this? Thanks.
