both get wronlgy redirected from time to time.
for examlpe, it's the same issue that haunted manyother people. The strange thing is, that I setup the extensions filter to omit links with activate&activation, and activate&token. It works for a while, and in few days - JoomSEF starts redirecting the links to users/activate, OR the homepage again.
Roght now i disabled sef all together for users extension, I need those registration to come in, but I will look into something that works soon.
As for the blank page - it is not a php error with white screen. It's a normall site saying usually something like "Your registration is almost complete, but check your mailbox for activation email", but this content is missing. Its just a template - no registration information, thus the users get really disoriented.
