XF 1.2 [Solved] Changes in one database affects the other database


Well-known member
I have XenForo 1.1.5 installed locally with Winginx and want to upgrade to 1.2. Because I have a lot of TMS edits I thought the best way to convert them to direct template edits would be to duplicate my XenForo 1.1.5 installation but under a different named database and use it to check each TMS edit and apply them one by one on my other installation because TMS doesn't work on 1.2 and I don't trust the current 1.2 compatible TMS beta yet to do the job without issues.

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?

You must have the same details for both installations in library/config.php.

You will need to edit that and change the database details to match each one.

You are right. I forgot to edit this file after I duplicated my xenforo files. Many thanks.
