I bought this module along with Pretty Names. Pretty Names works without problems, but the Pretty Names modules broke my whole site running on UNA 12. Blogs and forums are broken, to start with. International Unicode characters are not supported. Please either fix it ASAP or refund this purchase. Thanks.
We detected an issue that was causing error 500 in some PHP versions on non standard servers. In case you want to give it a try, please install version 1.0.9. If you can send us the errors log file we can see why is not working in your website and it will help us prevent this for other customers as well.
