Question marks at thumbnails on apple devices

Hi,

Very Nice add on, but I get these questionmarks at the thumbnails on apple devices. No mather what browser I use.
This problem does not exist on a windows 10 desktop...
Is there something I do wrong?

Greetings Michel

Weird, is the url to the image valid in the mobile browser?

Yes, it is valid.

Ok, that's even weirder. I would expect the path to be broken or something.
Is it WebP? If so, does disabling it do any difference? See Admin -> Settings -> Images

Are you using a CDN or similar?

Hi Tim,
No I'm sorry.
WebP is disabled and no CDN (use Hostnet)

I tried on a windows desktop pc in private mode and that won't show the thumnails either. the boxes are just empty
If I disable the image carrousell, all the tumbnails are back, even in private mode.

I really have no clue. If the URLs are valid we would need some sort of debug feedback from the mobile browser to understand what is going on.

The reason why you get this behavior with ALL mobile browsers on an Apple device is because they all run the same Safari embedded component. Apple does not permit other browser engines but Safari. So you would think you run Firefox, or Edge, but those are just the menus. They are all in fact Safari.

I fixed error not show thumbnails.

@tuthanika What was the cause of the problem?

@tim
I don't understand the code. I just compared the problem before and after add vmods, and fixed it to make it work. I fixed:
<img src --> <img class="img-responsive" src
$img --> $slide

Thanks tuthanika!
Good Job!
