Whilst I had no problems installing the subsites module on my localhost with wamp, I cannot get it to install at all - not even rebuild the databank when I upload the same subsite directory to my server hosted by domainfactory. Any ideas what could be the problem?

Do you get an error? If you enable display_errors in your php.ini and turn on dev mode on your live site (just for now) you should get a more helpful error message.

Thanks Willr.
I cannot get it to display any errors even with everything switched on. I just get the Silverstripe Web error banner come up. The browser error console does not show any errors either.

Solved the problem
Added: Director::set_environment_type("dev"); to mysite/config file
(I did this in an attempt to see the messages)
Then it surprisingly worked!
Afterwards I could comment that out and it still works.

If logged in as administrator, you can also add the URL-param ?isDev=1
this also enables development-mode for you.
This might also be handy...

Thanks Marc for the useful tip. It's just been beginner's luck to date.

I have tried installing subsites with the genericdataadmin module. when I try to access the site or run /db/build or /dev/build I get database errors regarding missing table for the sub-site.

Running the DEV mode, I see the error...

[User Error] Couldn't run query: SELECT `Subsite`.*, `Subsite`.ID, if(`Subsite`.ClassName,`Subsite`.ClassName,'Subsite') AS RecordClassName FROM `Subsite` WHERE (`Subdomain` = 'kidsmusiccompany' AND `IsPublic` = 1) ORDER BY "Title" LIMIT 1 Table 'kidsmc_ss233.Subsite' doesn't exist
