Help with - Liquid error comparison of Array with Array failed

I didn’t change any files or anything, but I couldn’t make any changes to my site after a certain point. On Github I am getting this error:

Thanks for helping!!

I’d recommend you always do small, incremental changes. This way it is easier to pinpoint which exactly change caused your issue. Without further information about which changes caused the issue it is hard to help you.

Try rolling back you latest changes to see exactly when this started to happen.
