 * Hi, that error has nothing to do with this plugin. Speak to your host, they should
   be able to help you. The following [thread ](http://stackoverflow.com/questions/10205722/json-encode-invalid-utf-8-sequence-in-argument)
   might bring some light into your issue.

 * Hi,
    Thanks for your help. I tried to analize your link. In that case he wrote
   about symbol �. I have the same symbols in some plugin messages, which I have
   translated to cyrillic (russian) by PO file. Also all my data of partners is 
   recorded in Russian. Is Affiliates Manager plugin support cyrillic?
 * Thanks, Dmitry

 * [@dmitrysh](https://wordpress.org/support/users/dmitrysh/), I will investigate
   this issue on our development site. What language do you have set in the General
   Settings (Settings -> General Settings -> Site Language)?
