Everyone that has complained here: get raped. I'm not going to use this account again, but a duplicate element that works is nothing. You're the type of nigga that has a breakdown when the ice cream machine is down at McDonalds.
Kengal or whatever you go by you really need to:
1) Enable daily backups of the server
2) Put EVERYTHING related to xenforo into Git or another source repo
3) Backup the content and styles folder daily. Those are the data you need to start a new xenforo instance so they're what you really need.
4) I have no fucking idea what Xenforo is, but the default is themes go into a database table. That is not the case here. I don't know why that's the case but it's far from optimal. The people that wrote XF aren't mega-geniuses for sure, but going against the defaults is a lost cause.
5) UI.X is trash. They couldn't even name their theme something that you can google. PEAK RETARDATION. It's like naming a child Xylophone.
Yes, I fucked up, but the pajeet you're hiring is going to fuck up as much as me but you won't even know. When the shit hits the fan they'll just disappear. SOURCE: I've worked with many Indian people and much about them is a lie. There are so many fake Patels it makes my head hurt.
