Sad to say, I’m testing now in PHP 5.5, and 5.6 and am not dealing with your same issues. My slideshow is loading fine actually, so I’m wondering where the problems are coming from.
@flavia-programmer – it looks like you’re dealing with a jQuery issue or else the javascript is loading before the elements arrive.
@simk it look like your error is dealing with decoster6.jpg – right in the middle of data-thumb for that image we get this:
<div id='satl-custom-13147' class='sorbit-wide absoluteCenter'
data-caption='#custom1-7'
data-thumb='https://www.philarchi.be/wp-content/<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>200 OK</title>
</head><body>
It’s a really strange bug! Can you try and delete all the images past decoster5 and see if the slideshow loads?
Thanks!
