I have installed the core of SS in a subdomain called "test" (and like what I see). I have tried to install more modules, but kept getting an out of memory error. I have scoured (for the last week) the forums and google, and have also asked my web host for a solution. The only way I can do this (after trying many other solutions) with my host is to add "php_value memory_limit 64M" to the root .htaccess file. I have tried heaps of permutations on this, but everything comes up with an internal server error, on both the root domain, and sub domain - only when this memory command is added. Help would be much appreciated - I can't evaluate SS further until this is fixed..

Can you look in your server logs to see what the error is. That command could have been disabled by your host.

I've looked everywhere for logs that hold some useful info, but there is none available to me. The host has recommended this setting, so I would presume that it is enabled.
