Some more information please.

Link to page?

Code?

Appointment - Exciting 4 Everyone this is the page where the script (purchased from PHPJabbers) should be displayed.
A php script software that needs to be installed separately on the server.
The software then creates a php script which I integrated into the EVO software.
In the example browser of the W5 software the script is displayed, that's the strange thing about it.

1) If the script is in PHP then the page must also be saved in PHP.
I see that yours is .html instead
Go to MAP - select the page, Properties and tell it the extension .PHP
2) in my opinion you are also inserting it in the wrong place/mode
check the script instructions...

I don't know the script and i don't know what the parameter(s) make - but - if you change:

<script type="text/javascript" src="http://www.exciting4everyone.nl/appointments/index.php?controller=pjFrontEnd&action=pjActionLoad"></script>

To

<script type="text/javascript" src="http://www.exciting4everyone.nl/appointments/index.php"></script>

You will maybe see something and then you can experiment from that.

You are using http and not https but as it is same domain it probably means nothing.

We finally got it working, the problem was that the script was installed in http environment instead of https environment.
This will probably also change the settings of the script.
Stupid of us, but we should have known better as our experience with PHPJabbers scripts has always been excellent.

Thank you very much for thinking along with us.

page in php and https... well !
