| | Test installation affects live site.
I copied my site for testing purposes. Unfortunately, running 2 versions of my installation didnt go well.
Even though they are two different databases with different database users somehow the configurations get mixed up. I dont know why.
As it was a copy of my live site, my test installation had the same settings as the live site. I changed this in the admin and the config files.
The effect was that not only the test site got updated with the test database settings, but also the live site got those settings.
Now every time I try to change it back, it has no effect.
What do I do now?
