So, I already did this for the vB3 version of this plugin several months ago. I had need to do a vB4 install too now, so I've done it for this one too:

I've repackaged this add-on into a 1.0.1 version, which you can download below. The main change is incorporating the required PHP fix (from above). So, this will work properly with vBulletin 4.2.5 and PHP 5.6/7.0/7.1. It should also work with earlier versions, though the minimum PHP version required is probably something like PHP 5.3.

I also updated all the UI elements to refer to the feature as "reCAPTCHA v2" instead of "New reCAPTCHA". I also updated the readme docs, correcting errors and typos.
