Hi, i’m Francesco Gregori from Multitraccia, Italy.

I’ve installed Lasso 9.3.2 on a MacOs 10.13 machine

Lasso is correctly installed, it sees my Mysql DB.
When i try to browse my solution many js components are not loaded correctly so i can’t run correctly my solution

If i try to browse single JS file at the end they reports same code:
<div class="container">
<img alt="Spitfire 500 error" src="/lasso9/lux/images/ise500.png">
<section role="main">

<header role="banner">
<h1>Internal Server Error</h1>

On a previous macOS 10.8 machine and lasso 9.2 my solution runs correctly but i must upgrade to a new machine
May be LUX server that does not serve correctly files?

May i use apache instead of LUX? How can i do?

Please, can you help me?

I thank you in advance
