Standard logout link problem

Yes, seems like an issue. I will fix it for the next version, this week.

I can't wait to see new version then.

I've noticed also that despite seeing new version in About section of component configuration, Joomla can't find it in Extension Manager: Update site. (Doing find updates finds other components ready to update, but SEF Advance is missing on that list)

Fixed in 1.6.8.

After installation of 1.6.8 logout link is not working correctly, it gets 404 on redirection to the following url:
starting point was as in the first post url in form of:

solution: com_users.php
if block for matching '&return=' should be in a top of function build or even better should be merged with '&([0-9a-fA-F]+)=1' matcher

I've noticed that all redirections in Joomla are using full, well-formed address i.e. method redirect() in application\web.php tries to expand urls so they always include joomla base uri (e.g. http://localhost/joomla/).

For reasons that I am not aware of, doing same thing in your plugin in process_nonsef() method solved me another issue related to logout link. (Correct logout url causes error 404 in production environment)
