My post here was closed. I have the same question as another user but I do not understand the accepted answer. To me, it appears incomplete. It is missing details which I do not know how to fill in.
How can I proceed?
Steps towards a solution:
If the user is somewhat active (e.g. visited the site in the last month or so), leave a comment asking for clarification and wait a few days. I get such comments every now and then, and that's fine.
If the first step failed, ask a new question. Put a link to the question, quote the answer, set up the whole context, and explain what is missing for you. Wait for an answer.
If the second step failed, study harder until you can answer your own question.
