Sadly, the server transfer didn't turn out the way I hoped it would. Turns out I'm not the most tech-savvy person when it comes to servers. I'm really sorry about that. I tried the best I can, but it seems like I still mismanaged the server-settings. Even though the testing seemed fine.
At this point, I'm turning to friends and colleagues to help me out with the server. Hopefully, I can find someone who can help us out with it on a regular basis. Sorry if I have disappointed you! I'll try the best I can to fix it and make up for it. Please bear with me while I try to manage this all.
