At admin UI, at the Pages list I right clicked and selected to run the "Test Pages" tool
(Interesting one btw, but while it works you can't scroll down, it keeps scrolling back to the top after each text append it does)
I noticed the following entry there:
2014-07-08 15:38:48Z: http://social.clipflair.net/profile/Salomé/
2014-07-08 15:38:48Z: Bad Request
notice the last char at the username Salomé
However, if I paste http://social.clipflair.net/profile/Salomé/ at the browser addressbar it brings the page OK, so it must be some error with the Testing utility, probably it needs to encode the URL for each page before trying to access it (guess .NET requires that, whereas browser address bar does it automatically)
