Alpha 2.2 is now available for download and testing:
This version fixed several bugs.
Alpha 2.3 will continue to fix more possible bugs + add support for no mod_rewrite as suggested by CJPinder.
Feedbacks are appreciated.
PS: as of now, Simple Seo Url is still under development and NOT recommended on live site. The more feedbacks and bug reports, the sooner it will be available for use.
