First of, yesterday hugo was working. But I was running hugo from a download sub directory and after cleaning my download I had to get a new hugo for my WIN 10 OS.  
Therefor I fetched myself a brand new hugo win 64 ext. (since the used liva template needs the extended hugo version for CSS). And also install git brand new to my PC.

Link to my Repo with the Sources:

I am using the liva theme form “Themefisher”

Who can help me reading the error messages to get my website rendering again? Many Thanks.

1. Guess: I messed with the taxonomies yesterday eve: Changing them in the front matter of posts and deleting the URL output in the index sidebar partial, so that the tags are listed but not clickable.

**Executing** :  
“hugo server”

**This is the result** (I switched “.” to “(dot” so that it is not counted as a link):

Hi there,

Thanks. I did and I also reached out to the theme provider team in Github.

Will my issue be handled or did I miss out something from the “Requesting help” manual?  
Thanks for the update  
Chris

There’s this whole chunk:

> [@](#):
>
> ### Let us see your code
> 
> Include a **link to the source code repository** of your project, because we really need the _context_ of seeing your templates and partials to be able to help you. It is trivial to do a quick `git clone` on your repo, then run `hugo server` in your project, to help you out. On the other hand, recreating your code from screenshots, or sort of guessing at it, is not.
> 
> If you can’t share your repository for whatever reason, consider creating a dummy repo that you _can_ share, which reproduces the problem you’re experiencing.
> 
> Git repository hosting services include [Github](https://github.com/), [Bitbucket](https://bitbucket.org/), [Codebase](https://www.codebasehq.com/), [Gitlab](http://gitlab.com/), [Sourcehut](https://sourcehut.org/), and others. If you select Github, even if you do not know `git` or have a repository, you can use Github “gists” for pasting logs and files. You can include multiple files in a single gist, like [this one](https://gist.github.com/RickCogley/2f0d21144e5f3091e62a6ced211c71f3).
> 
> ### Are you using a theme?
> 
> Consider contacting the theme’s author, if it is a theme-specific question because often the author will know better than the random passer-by in the forum. Check the theme’s README. But at least include a link to the theme, to help a person trying to help you.
> 
> ### Include Output and Environment Details
> 
> First, use the `--verbose` switch on `hugo server` to produce more details on the command line including about errors.
> 
> Include the output of `hugo env` from the command line, and any other relevant versions.

Please also note that we are all volunteers here. People answer questions when

1. they know the answer,
2. they have time.
