In other words, I have the following installations:
A) XenForo 1.2 (updated from 1.1.5 with no TMS installed), database name: xenx
B) XenForo 1.1.5 (with TMS installed including all TMS edits), database name: xeny
The problem I noticed here is that any changes to either database affects the other. If I create a thread in my xenforo 1.2 installation, the same thread is created in my xenforo 1.1.5 installation and vice versa. Why is that and how can I avoid it?
