Hello, so the situation is:

Warning: Invalid CMS Database. Please go back to Step 1.

I'm runing 2 hosts.
-1 webserver (in where azer cms files are installed in an apache2 server).

And the ingame host.
-2 ingame host (in where auth, chars, world and azer cms db are hosted in mariadb default port 3306).

So i'm not sure what can be problem i been trying for awhile and still no results, if anyone could help me any configuration and so on i will be really grateful! greetings.

The CMS was written with the explicit intention of being hosted on the same machine. So there may be issues with attempting to use an external web-host. I don't remember what all had to be changed.

I hope to fix this in another project that I'm going to be working on, but there is a possibility that v4.x may have not have this issue.
