This is a request to edit a HTML (and partially PHP) website. ([login to view URL])
Few things to be done:
1) Add Whatsapp-call button (will give you the phone number) on the place on the left under "WIEWIENEKE de sfeer-express", so it is "mirrored" with the "Boek mij op Gigstarter"
2) Add a Live Chatbox that pops up when you visit the site (pop-up something like "Hello, you can contact me immediately through this chatbox and I will reply instantly"), and should be possible to reply on the messages from a Samsung phone (please give me suggestion of relevant chatbox apps). Take into account that the website is now fully HTML, so might not work out of the box. Chatbox should have possibility of having Dutch / Nederlands language.
3) On the page [login to view URL] you get an error when accessing through certain Browsers, it's because the "Prijs" module is not supported anymore in Chrome probably because of too old code.
Error: "MuseJSAssert: Error calling selector function:TypeError: Cannot read property 'required' of undefined"
Also : Upon reviewing your website files, it is using outdated scripts that are no longer supported within the latest version of browsers specifically Chrome, hence, the message log.
If handier to implement, it's allowed to port to php or whatever.
