And if i'm not using MySQL and type /pets i've got these output:

Your first error is because you have an invalid config... This is most of the time caused when you use tabs instead of spaces, an easy way to fix it is to reset the config (Stop the server, delete the config, then start server).

As for your second issue that is caused because the values it is looking for in the config can not be found (due to the invalid config)

I have deleted the directory Simplepets and have it recreated again.
If I do not adapt anything it works fine.
As soon as I write just after blocking Worlds: -pvp following -pvparena1 appear in the console error.

[brainsynder-Dev]

That's because it is not in the correct format. Here is the correct format for your example:

blocking Worlds: 
- 'pvp'
- 'pvparena1'

Hmm, there are no '' characters in my config.yml and they do not exist on the webpage either.
I wrote the following:

• 'pvparena1'

After a server restart the Config.yml was reset automatically

• pvp
