Bob, before going with your suggestions I have just tried to run Everett Griffiths test config utility, I uploaded the php file into /home/mysite/my_new_site/public_html/ ... at the same level where index.php is and then I run
http://myURL/test_config.php and nothing happened, just loaded the main page of my site, like the test_config.php doesn't exist.
Tha same happens when I try to run setup. But it works with manager, the manager utility is loaded properly.
This thing about Modx drives me crazy. I wish to be able to locate the path in the server using the URL, for example if my URL is
http://myURL/assets/css/main.css I wish to be sure that the file is stored in /home/mysite/my_new_site/pubic_html/assets/css/main.css ... but I'm not this is the case. If I open
http://myURL/assets/css/main.css the main page of my site is loaded, ignoring the URL I wrote.
Probably this is related with Friendly URLs you are talking about, to be honest I don't understand very well that concept ... I need to research. As I said I'm pretty new to this and also not really aware about how Apache and Modx work together in order to manage URLs.
