InstallPoint do the first issue "Establishing the PATHs and URLs to files" fine, but the second issue "Creating folders and transferring necessary files " display the following error:
------------------
Your server does not allow scripts to create files.
It is unsafe to install any content management system on this server.
InstallPonit has aborted the installation.
Could not create /home/httpd/vhosts/spirulinamaxima.com.mx/httpdocs/editwrx/test.txt
--------------------
What I do wrong or do I nedd a change a setting?
Your server is not running the suExec utility. SuExec is a wrapper that forces a script to run as the owner of the script. Since the owner of the script is the same owner as all of the files and directories inside the domain, the script running with suExec can write to files with 0644 permissions and create files and directories in a directory with only 0755 permissions. Since your server is not running suExec the installer cannot create a test file at the point where you are getting the error message.
SuExec is a server wide utility that can only be installed by the server's super user. You need to ask the server admin to install it.
