Images not loading

Hello,

I have been using your plugin for years - It works great!

I recently upgraded your plugin from 3.5.4 to 3.5.14.

At the same time, I upgraded WordPress from 5.8.9 to 6.4.3.

Prior to these updates, your plugin worked perfectly.

I saw some posts about old sliders not working with the new software so I created a new slider and inserted it into a test page - URL supllied.

The four images begin to load but never get there.

I have cleared both browser and server cache.

When I inspect the code, the 4 URLs are present.

Using one of the image URLs, I can view the image in a browser.

What would be preventing these image from appearing?

Thanks in advance,

Kent
