Comment:

 Yes, looks like some corrupted files. It's an old blog (installed in 2009
 :) that I visited and had some fatal error (`Cannot redeclare class
 WP_Roles in /web/blog/wp-includes/class-wp-roles.php on line 26`).
 Fixed just to make WP run and it auto upgraded and then came the above
 mentioned error. Maybe it was 4.2.5 (had errors) then upgraded to 4.2.7
 and then 4.2.9 :) Sorry, but really weird. As I mentioned an old blog with
 low traffic.

 Yeap, running 4.2.9, check source at http://www.optimalizaciaseo.sk/blog/

 What blow my mind were the files (wp-rss, wp-rss2) I saw after connecting
 to the FTP

 The error log of my journey is at http://pastebin.com/v3TyF1qE (the
 WP_Roles error was there from 26th June 2016, I don't have older logs)
