Hi. I had a problem. I attached a hostname to an article in Umbraco. Afterwards I deleted the article and I wanted to put the hostname on another article.

My problem was that this was not possible. Umbraco remembers a hostname also if the corresponding article is deleted.

Sebastiaan from Umbraco provided the solution. In the Umbraco database hostnames are stored in a table called "umbracoDomains table". If you remove the hostname from that table Umbraco will be ready to attach the same hostname to another article!
