a short history...
CDN provider turned off their shit about when this thread started. I updated the theme at the time but missed some overrides in the xenforo config file so avatars, images and some javascript stopped working.
Last Sunday I tried to upgrade xenforo to v2. To do this I had to uninstall all addons, including tapatalk.
The upgrade failed, because... PHP version unsupported by xf2 so tried to upgrade php, but it's compiled from source and part if apache2. So recompiled upgrade from source but that failed cause ubuntu version is out of support. So upgraded ubuntu but that failed as the repositories are no longer maintained.
Meanwhile the server is still running, but ssh / sftp don't work so challenges everywhere. So restored server from backup last week, and tapatalk is borked.
This server was my first shot at linux, pretty happy it ran for almost 10 years, but it's time for an upgrade. So now we're starting again. New server is in Sydney with East Coast Bias hard-wired into its' core. It's a off the shelf LAMP server very few customisations, and we'll hope to turn off a lot of the shit that's accumulated over the years and get back to something that can be supported.
New system is close, maybe this week. It's running the latest wordpress and xenforo 2.02.
