problem to access the admin

I can come to the page where said

If You have reached this message than the system is INSTALLED.

- Go to the admin panel ("admin" button after the setup is finished or ADMIN .
- Also you can read the documentation following this link: MANUAL

But when I am trying to go to ADMIN section, the webpage said:
error 500: Internal Server Error


The server encountered an unexpected condition which prevented it from fulfilling the request.

Any help will be great!!

Internat Server Error is when ISP restrict BASE64 autentification mode.
The solution is to open authenticate.php from includes directory and
delete all from it and copy this.

<?php
$AUTHENTICATE=1;
?>

BUT, be aware, in this way is no PASSWORD required.
So, please add .htaccess autentification.

So where do I add the .htaccess authenication?

In new version you have a configuration panel in ADMIN part, where you can do this now selecting autentification mode.

I tried putting

<?php
$AUTHENTICATE=1;
?>

in the includes directory, and I installed the tables and stuff, but I still get the 500 error. I can't get to the admin part.

btw I have the shareware version.

Now is not in autenticate.php, now is in tmp/extraconfig.inc.php, open that and there is a line

// 1|LANG_CONF_D_AUTH_TYPE_BASE64|2|LANG_CONF_D_AUTH_TYPE_SESSION
define("AUTH_TYPE","2");

Change to 1.
The ideea is that this will be overwritten when you modify from Admintool/Configuration, so be sure that also there you will choose BASE64 autentification.

So change it to this?:

// 1|LANG_CONF_D_AUTH_TYPE_BASE64|2|LANG_CONF_D_AUTH_TYPE_SESSION
define("AUTH_TYPE","1");

Because that still didn't work.

Can you send to us (in MAIL) FTP details to see why not work?

OK I sent it.

Would you be able to show me an online demo or something so I can see what it is like?

www.gtstelecom.ro, www.integrasoft.ro is doen with this software, we do not have online DEMO.

When I get to the admin section, it asks me to log in. However there wasn't a place that I had to define this info. So I really don't have a username and password to log in. I can't log in to the admin at all. How do I set this? There wasn't anywhere during the installation to set it.

The default username and password is demo / demo.

thank you. I've logged in successfully.
