I use site_upgrade plugin when I do some maintenance.
I noticed something strange: when site is closed, the main link (domain_name) is redirected to site_upgrade page.
but for rewrited link, as domain_name/page/gallery, the redirected link is:
domain_name/page/gallery/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/plugins/site_upgrade/closed.php
and of course it is wrong and causes an error in my browser (FF).
you can see it in action here:
http://test.vincentbourganel.fr is redirected to http://test.vincentbourganel.fr/plugins/site_upgrade/closed.php
and with http://test.vincentbourganel.fr/page/contact there is a bad redirection.
the issue is not occured if site is in test mode.
