I am sorry for saying this, but whole phpSysInfo is extremly difficult to integrate as 3rd party extension (e.g. into framework). This is caused due to hard-coded URL links, which dynamically load contents. Instead providing mechanism to submit own URL ROOT there is always hard-coded "./" webroot, which is OK only if somebody copies files directly under webroot - but in any other case it does not work.
Is there any chance to add such a simple function:
$webpage = new HtmlOnlyNoLinks();
And yet, if he want to do some custom CSS styling, he can do with his own CSS defined outside of this HTML content.
I have spent couple of hours trying to fix all bloody links, but it's just too much time:-(
