Hi Greg,

It seems there is some conflicts on WP 4.4 in my site.
I got several Warmings in my blog section like this:

Warning: Invalid argument supplied for foreach() in […]

I could manage that issue googling and changing the code line by line.
It seems that something is wrong on foreach() arguments so it has to be past through array()

I solved this in two different ways adding array() on foreach() arguments like this:

foreach ((array)$values as $value) {
// …
}

And this:

if (is_array($values)) {
foreach ($values as $value) {
// …
}

Now my problem is solved. I just wonder if this was a issue for more people.

Many Thanks for your consideration.

I too would love to know how to manually hard-code the checkbox into the registration-form.

I like Newsletter Sign-up plugin because of the “Sign me up” checkbox.

Does Wysija! do that?

Thank you.
