can you please give more Information what your Pull Request is for also Test Instructions?

I'm sorry, but I don't know how to answer that. I'm unfamiliar with how Joomla works, so I wouldn't know if it's a configuration issue, which for me, it seems not.
Our company website, throws these notices: https://jeppe.ch/i/3RsAkepH.png - So this PR is just a simple check for, if an array property exists, as the title says.

Please ask help on the forums. This repository concerns Joomla coding. For this Reason please close this Issue, thanks.

@franz-wohlkoenig This is a legitimate fix.

@franz-wohlkoenig I don't see how this is not an issue, as Joomla obviously fails to check if an array property exists.

@jeppech sorry, have your Comment understand wrong.

This is really testing my patience.
@Quy, what do you want me to test? The unmergeable PR, that hasn't been touched in two months? Or his implementation of the issue? Both of them works.
It's frustrating too see, that a 24 chars commit can start all of this.

Can this be reopened? We might as well have 3 solutions to the same problem open.

@mbabker can this please reopened? Tried at Issue Tracker got 422 RuntimeException Invalid response from GitHub

Can't be reopened, source branch for the PR has been deleted.
