Are you sure it is not a firewall block or proxi or reverse-proxi redirection ?

The link you try seem direct to your main domain.
Is it the url you get when you access ProjeQtOr ?

Can you also try and have right click on id of the expected item.
This highlights the url to the item, just copy it and paste value in browser.
Do you access item ?

When i copy the hyperlink "projeQtOr " item is deleted....

See:
http://www.pactenovation.fr//view/main.php?directAccess=true&objectClass=Action&objectId=313

If i add "projeqtor" , it is ok

https://www.pactenovation.fr /projeqtor/view/main.php?directAccess=true&objectClass=Action&objectId=313

When i copy it in the browser, the link does not work..

OK, so you're missing beginning of the URI.

What is your PHP server ?
(I would bet for some f...g IIS 👿 )

Here after information that you need:

Apache 2.4
PHP 7

On wich infrastructure ?
Windows with IIS ?
Linux ?
Windows with WAMP ?
Else ?

Information that you need:
Reverse Proxy -> linux (centOS)
Web Projeqtor -> LINUX (debian 8)

Hi,

I guess it is configuration of your reverse proxi that gives unexpected result in PHP configuration.

Could you please :
1) add 1 line after line 4078 in /model/persistence/SqlElements.php, this way

	public static function getBaseUrl(){
		debugLog($_SERVER);

2) in your paramters.php file, set

$logLevel='3';

3) go to any item and click on ID of item (this will show the url)
Post here result written on log file.
