I have installed silverstripe once, but now I have to uninstall it (memorylimit only 16mb)
The problem is that silverstripe is still in my system. When I go to mydomain.se I get this message:

Not Found
The requested URL /sapphire/main.php was not found on this server.

What should I do to completely remove silverstripe. I dont have permission to clear cache at my hostingcompany.

Thanks!

If you're having trouble with php_memory, maybe you could try setting this in
your htaccess-file to increase it:

php_value memory_limit 32M

Some hosting companies allow this, mine did anyway...
