Hey, @tgxworld, I’d this related to the problem that you mentioned in another thread that I can’t find right now on my phone?

5

I’ve seen this error before. Try looking for “tabs” in your app.yml, and replace them with “spaces” (yml doesn’t like tabs).

6

Thanks for your reply, there are no tabs in my app.yml, checked it already.

Maybe someone can give me the default app.yml and i will change it

7

It’s in the templates directory. Standalone.yml.

Thanks found it
