I would like to know this as well..
The All in one security plugin, can change the wp
-admin login path, and right now my sites are under fire from brute force attacks, so I would like to install the All In One Security plugin
The only problem is that Classipress do redirects as well so the login is handled by a frontend page and not the "Standard" wordpress login, so I fear that there could be an issue with the all in one security plugin and classipress.
But since the site is live I can't not really mess with it, and it needs some serious testing.
So have anybody used this plugin with classipress?
