Javascript conflicts after upgrade to WordPress 4.8.1

Hi,

I’m using Boxzilla 3.1.16

I’ve currently got three boxes defined, one of which is actively referenced in the site. Here is the text in the three boxes:

1. Sample box, testing an embedded link to close the box:

Some sample text
Close this box

2. Box to display test signup form for MailChimp for WP:

[xyz-ihs snippet=”Link-to-dismiss-current-Boxzilla-box”]
[mc4wp_form id=”223″]

3. Box to display test signup form using MailChimp’s own form:

[xyz-ihs snippet=”Link-to-dismiss-current-Boxzilla-box”]
<!– Begin MailChimp Signup Form –>
… then a large amount of embedded html provided by MailChimp

The embedded MailChimp html is quite extensive, I could place it in a separate post below. Or better still, I would prefer to email it to you if needed as I don’t really want to publicise our email list details in this forum.

It is box (3) that is currently referenced on the site. It is called up via a sidebar text widget containing text:
[xyz-ihs snippet=”Show-box-for-MailChimp-signup”]

I’m using the XYZ Html plugin because the WordPress 4.8.0 upgrade changed text widgets so that they stripped out Javascript calls in visual mode. The same thing happened when editing your boxes, hence the use of the snippet in the boxes to include the “close this box” link.

I see that WP 4.8.1 has introduced a new html widget, doubtless in response to the outcry after they changed text widgets. So I may be able to do away with the current “html snippet” complication, but this is my current setup.

The snippets referred to above contain:

Link-to-dismiss-current-Boxzilla-box:
Close this box

Hope this is of some use. I’ve no time for more now but happy to give more information later. Thanks!
