Hi Jeff,
I am having a similar problem. I have this plugin on 2 sites. I am using the latest WP 2.9.2 with the Genesis them framework on both.
On one, the upgrade just stopped at ‘reactivating the plugin’ and then went completely blank. I had to ftp and remove the entire plugin to get access again. This had also happened when installing the ‘theme-my-profile’ so I had switched to the ‘login’ version of yours. What also isn’t happening on this site is the strength meter. Since this mornings first upgrade it fixed the problem of matching passwords, but not the meter. Although the second upgrade causes the blank screen.
On the other, both upgrades went through and the strength meter works, but the titles are still showing all the excluded pages on the profile page.
Thanks,
Nina
