CMS Made Simple Forums

I´ve got CMSMS running for a while now, and it's working fine. The site has a login
page in the beginning, so you can't visit without a password. Now the problem is that
the site should offer a alternative language in the beginning. I thought I could just
install another CMSMS in a new sub-folder, like this:
www.mysite.com/cms (original)
www.mysite.com/cms/v2 (second language)
(made up addresses)

but this causes all the changes I do in either Admin panel to change both the
sites. So I can´t change just one of the sites.

How should I solve this problem?

Thank you!

Are they using the same Database? If they are maybe that is the problem then.

I´m actually not sure about that. How can I find that out, and if they are, change that?

Seems like this could be the solution, but how do I actually get it up and running?
I have the old (one-language) page running, so where do I upload/install the
multiland package? If I replace the old one, I´ll lose everything I´ve made so far.

It's not easy but there are two ways possible

1. Create a database backup, create a new CMSms multilang installation. Then open sql backup and search for inserts you need like e.g. content etc. and import it via phpmyadmin.

2. You can modify your database so it will work with CMSms mulitlang. Compare database from a fresh CMSms and a fresh multilang installation so you can see what tables must altered. On install procedure you have to uncheck fields "Create table" and "Install defaul content".
