Hugo Version 0.62 doesn't render correctly

I want to Update to version 0.62. I put this lines into the config.toml

unsafe = true

Then the buttons looks correct and they works fine. Without these lines there are only the link name.
Here is the shortcodde for my buttons:

<a class="{{.Get class}}" href="{{.Get href }}">{{ .Inner | markdownify }}</a>

Here another shortcode:
<div class="{{ with .Get "class"}}{{.}}{{end}}">{{ .Inner | markdownify }}</div>

That is not the only problem. There are some css frames whitch not correct rendered.

Please share the rendered output and what you expected it to render.

When I run hugo server I get this error:

Error: add site dependencies: create deps: failed to create file caches from configuration: mkdir /tmp/hugo_cache/old-developer: permission denied
I never needed to login as root user to run hugo server. Maybe this could be the problem.

[pse@robbie developer]$ su root
[root@robbie developer]# hugo server

It seems to be okay, but there are no links and no buttons. Please see the screen shot

Then I added this lines into the config.toml:

unsafe = true

I deleted the cache from my browser and tried again.
Here the screenshots:

At first the look of the buttons and links.


Here the screenshot of the code boxes:

Hugo needs access to a cache dir. You can set it to something else with the cacheDir flag/setting.
