Edit Your Details page shown first

Are you using any other third party extensions, such as Community Builder or JomSocial, that may also manage the user's password? The reason I ask is because in Joomla 1.5, there is no specific change password page, just the my details page where the user can change their password.

SAE,
Sorry for the delayed response, the holidays slowed down our response time for the non-commercial extensions. The purpose of the Force Password Change is to send the user to the Edit Details page when they first try to login to the site. It sounds like that's operating properly. I'm not sure what page you actually mean the user is being sent to the 2nd time when you say "it then directs me to the change your password page. "

That sounds like a different extension other than core Joomla, which is why Melissa was asking if you're using something else. If you're still having this issue, can you post the URLs (doesn't need to include domain) of the 2 pages your seeing? It sounds like one of those pages should be:
index.php?option=com_user&view=user&layout=form
That page is what the Force Password Change plugin should redirect the user too. Please let us know if that's one of the two pages you're seeing, and what the second page is as well.

Thanks,
Alex
