Xcode Webview items not loading - swift

Question

I have a Xcode Project with a Webview and a TabBar and with the TabBar I can switch between WebViews. My Problem is that when I put something in my ShoppingCard under Lieferworld.de and switch with the TabBar to my Shopping Card url the Items in there are not Visible. How can I solve this? the ShoppingCard URL ends with .php. Below is the code which is implemented
I also uploaded a video on YouTube were I you can see the error

Viewhome:
import UIKit
import WebKit
class viewHome: UIViewController, WKUIDelegate {
#IBOutlet var webViewHome: WKWebView!
override func loadView() {
let webConfiguration = WKWebViewConfiguration()
webViewHome = WKWebView(frame: .zero, configuration: webConfiguration)
webViewHome.uiDelegate = self
webViewHome.configuration.preferences.javaScriptEnabled = true
//webViewHome.configuration.preferences.javaEnabled = true
view = webViewHome
}
override func viewDidLoad() {
super.viewDidLoad()
let url = URL(string: "https://lieferworld.de")
let request = URLRequest(url: url!)
webViewHome.configuration.preferences.javaScriptEnabled = true
//webViewHome.configuration.preferences.javaEnabled = true
webViewHome.load(request)
}
#IBAction func GoBackHome(_ sender: Any) {
if webViewHome.canGoBack {
webViewHome.goBack()
}
}
#IBAction func GoForwardHome(_ sender: Any) {
if webViewHome.canGoForward {
webViewHome.goForward()
}
}
}

WKNavigationDelegate has three delegates.
Here's an example;
func webView(_ webView: WKWebView, didFailProvisionalNavigation navigation: WKNavigation!, withError error: Error) {
print(error.localizedDescription)
}
func webView(_ webView: WKWebView, didStartProvisionalNavigation navigation: WKNavigation!) {
print("Start page load")
}
func webView(_ webView: WKWebView, didFinish navigation: WKNavigation!)
{
let title = webView.title
print("finish load. \(title).")
// you can do processing on the results here or trigger processing elsewhere
webView.evaluateJavaScript("document.documentElement.outerHTML.toString()",completionHandler:
{ (html: Any?, error: Error?) in
print(html as Any)
self.htmlSource = html as! String
NotificationCenter.default.post(name: NSNotification.Name(rawValue: "pageLoaded"), object: nil)
})
}
