User profile for opencaching

I've read somewhere here that user's profile (logs tab -> tap user log -> show user profile) does not work for opencaching. Now (2.20.1 )I've noticed there is only message "Unable to display user's profile". But there is a way to resolve this issue. You must use OKAPI for opencaching. There is an okapi method which returns user's profile url where input parameter is user name:

http://opencaching.pl/okapi/services/users/by_username.html

For example:

1. http://opencaching.pl/okapi/services/users/by_username?username=

   USER_NAME

   &fields=profile_url&consumer_key=YOUR_CONSUMER_KEY

Input parameter USER_NAME taken from log,

YOUR_CONSUMER_KEY can be obtained from:
