Hi, the fix works for me. $data is already an array and initialized with labels a few lines above. I don't see the reason to use is_array(), a check with isset() should be enough.

Hi, here is the patch based on #5 to review.

I applied the fix in #7 and it removed the notices. I will report if anything changes going forward.
Thank you.

I had the same issue.
I applied the patch in #7 and it works.

#7 works for me also! Can we get this commited?

+1 on patch in #7!
