What are actively maintained, good, open source, traditional forums software in late 2018/early 2019? I currently have two forums running SMF 2.0, but SMF is increasingly becoming no longer an option. The last version of PHP that SMF 2.0 supports is 7.1, which reaches EOL next year. It's been stated by SMF developers that support for PHP 7.2 or higher is not coming until SMF 2.1, which has been in development for several years now with no end in sight. Who knows when (or if) SMF 2.1 will see release. It's a shame as I've been a SMF charter member for years, but it is what it is. I try to use and support open source software where possible, so are there any actively maintained, good, open source traditional forums software to transition to? From what I understand, phpBB has been plagued by security issues for years, and does not really support mobile devices well, (much like SMF 2.0). Also from what I understand, myBB has been in the same state of inertia as SMF. There's Discourse, but that's not really "traditional." There's also Flarum, but it's still in beta and again is not really "traditional." I own licenses to both IPS and WoltLab Suite Forum, so I don't mind spending money. Worse comes to worst, I'll just transition both forums to either IPS or WoltLab Suite Forum. But, again, I'd rather try to use and support an open source forums software if possible.
