ips 4.6.4

Hello all, downloaded a application for Discord integration. After looking into it and when I went to start the config of it. It produced that error below. I tried clearing the cache upgrading php version but nothing has helped. Is it because I'm running ips 4.6 or is there another reason I'm...

Hello all, So of course im on an older update of IPS board I think like 4.6 or something like that. Is there any easy way to upgrade to the newest one by chance? I know if you buy the expensive software is does automatic updates and keeps your files. Just wondering thank you!

Playing style for IPS4.
