Helen,

I tried, and I don't have problems to connect to that site (IE, FF, Chrome) - "Bine aţi venit pe Portalul Universităţii TRANSILVANIA din Braşov!"

If you still have this problem, it is propably something in your browser cache.

Happy DNNing!

The issue is with access to admin and host settings. I can connect to the site, but after I logged with host account  I cannot access the Common Settings and Advanced Settings. When I click the Site Settings the following error appears: 

Firefox can’t establish a connection to the server at XXX:
* The site could be temporarily unavailable or too busy. Try again in a few moments.
* If you are unable to load any pages, check your computer’s network connection.
* If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web.

What can I do so that I can access these sections?

Thanks,
Helen
