I decided to use the Kitto script to try to make a pet sim on AlterVista. I followed the documentation and the errors on my site never went away after I finished installing the script. I think it may have been because I didn't chmod the directories, but I didn't know how to do it in AlterVista. Here is my site. Kitto doesn't have an active forum/contact section so I'm stumped.
Finally was able to get it fixed! So, the issue was that I didn't have the right paths for the Smarty template directory and HTMLPurifier cache. To get the path, I had to check system_check.php, which lists the base path when looking at your file directory (in AlterVista it's under "File Management").
So let's say the path was: 'base_path' => '/membri/YOURSITE',
So the smarty template directory is therefore : 'template_path' => '/membri/YOURSITE/template',
And the HTMLPurifier cache path was: 'htmlpurifier_cachedir' => '/membri/YOURSITE/cache',
