Because I have multiple domains I wanted to install Joomla for each domain.
I installed one with a RPM from Dietmar Berteld's contribs and one using SiteMaker. If I do so, when login as administrator in the second installation, I see the first installation.
So one way or the other both installations are influencing each other. Both are installed in differend directories in /opt and have separate databases and users.
Am I doing something wrong or something that won't work anyway?
I could always install Joomla in an Ibay, but I don't want to do that because of the security risks.
