PHP Vulnerability and MEM

Posted by admin · 14d ago · 0 replies

As you may have read in the news recently, there's been a couple of nasty vulnerabilities discovered in the PHP programming language, which is used by millions of websites across the planet, including MEM (the forum software is implemented in PHP). Newer versions of PHP (8.5+) have already been fixed; but older versions will not be addressed.

The bad news is: We're running on an older version of PHP, one that won't be patched, and I can't upgrade to a newer one because SMF 2.0 doesn't support them. To do that, we'd also need to upgrade to SMF 2.1, which is a MAJOR job - and, I know from other forums that have made the switch, there are enough differences between 2.0 and 2.1 to cause significant friction with users (i.e. you lot  ;D ).

The good(ish) news is: Because I recently moved us to a new server & a new containerised system (docker, for those who know what that is - if you don't, it's not vital to the news), so we're already partly protected. I've also just made some configuration changes that SHOULD make us pretty much secure. It's not 100% guaranteed... but fingers crossed: And even if they do get into the system, they're stuck in a container they can't get out of, which will significantly reduce any damage they could do.

With regards to the database - the DB is backed up nightly, with one backup retained for a week - so if anyone does notice anything funky, as long as it's reported quickly, we'll lose at most 1 day's worth of posts.

Unfortunately I'm severely time constrained right now, which means I don't know how much of a chance I'll get to do a trial migration to v2.1 + upgrade to latest PHP + patches; but I'll try to fit it in if I can. Then I'll need some volunteers to take a look at it/test it to make sure the new user interface isn't going to cause problems.  I'll post any news up here & in the chatterbox board.

Forum Migration

Posted by admin · 27 May · 3 replies

Hi all,

After a bunch of work (mostly by AI  :Jester:), I think I'm basically ready to move the forum to a new server. This server is much more up-to-date, and also the way it's set up means that future migrations should be considerably less painful.

At this time, I plan to do the work sometime on Saturday or Sunday the 30-31st May. I'm hoping the downtime will be fairly minimal, less than an hour to do the actual migration. I'll put the forum into maintenance mode about 30 minutes before I start, so any posts that are being written at the time should post OK.

The other difference between the new server and this one, is it implements a "soft firewall" - so if your IP gets blocked by a rule, you'll be redirected to a page which will give you an opportunity to have someone unblock it. Thus I can add whitelist rules to hopefully fine tune the anti-spammer stuff.

Onward and upward!

Unexpected downtime - Fri 24th to Sat 25th Apr 2026

Posted by admin · 25 Apr · 0 replies

Hey all,

Please accept my apologies for the unexpected downtime over the last couple of days. This was caused by some emergency maintenance + a migration from the physical host that runs our server to another one. This happened yesterday at around mid-day UK BST. Unfortunately, for various reasons, I've been insanely busy at home & only just checked it now (around 9pm UK BST). Following the migration/restart, the database needed manually cranking to get it running again.

Also, it seems we've run out of disk space again... so there might be a few more bumps whilst I make some room...
