Take a moment to read Requesting Help. That has guidelines for asking questions and getting help in these forums.
And to be clear, we all volunteer our effort to answer questions here, so we expect everyone to be clear and concise when they have questions.
It sounds like you lost the source files for your site or something. That is unfortunate, and we can’t do anything about it. If you have a specific question about Hugo, please ask it, and include a question mark.
