Grav 1.7-rc2, once Grav 1.6 is updated to RC2 error on Plugins Page in Admin

[paulhibbitts]

I've been trying to test RC2 in all of my skeletons, but I seem to be getting an error after I update Grav to RC2 (which works) and then go to the Plugins Page in Admin to update the needed Plugins:

The front-end of the site works fine.

Here is the entry in the Grav log:

Please let me know if any additional information is helpful.

Thanks very much,

@paulhibbitts Check my fix and try it out. :)

[paulhibbitts]

Thanks very much @mahagr , but the issue still seems to be there?

I updated my local test install with this commit:
185e9b5

Did I miss something?

[mahagr]

It should fix the issue as the $instances cannot be anything else but array after that.

[paulhibbitts]

Let me try to test things again @mahagr ...

[paulhibbitts]

Awesome @mahagr , that worked! I must have made a mix-up with my first test, thanks very much!

[MakaryGo]

@mahagr any chance to push it to GPM? As for now after update to RC2 via command line it's still broken :)
