How to edit my own post ten days after posting it

Hi, I posted a question in this forum ten days ago and it wasn’t answered by anyone. I want to edit my own question because I now have a simple sample code and I’ve got a bit closer to the solution. I don’t see any option to edit my own post, why is that? What am I supposed to do otherwise, delete it and create a new one?

I guess you have just around 10-minute to edit your post… so, I think you should just add a reply on the previous one… sorry, if nobody answer, but let’s suppose that everybody is occupied or maybe don’t have an answer. But in neither case, please provide with all the information you have available and take your time to post your question…
