Hi,
i first tried to install joomla over FTP, but couldnīt upload the files because i got a "Not enough memory" warning.
After deleting the uploaded files, then i just installed Joomla 1.7 with Softaculous, but there is still the standard x10.mx Welcome site:
This account has just been created. You are able to modify your account ...

What do i have to do, to get the installation/ site working?

Softaculous Info after Installation

Installation Time Today at 9:41 am
Path /home/musmur/public_html
URL http://emtek.x10.mx

thanks and regards
