Sounds like a Operating System issue. Sounds like the latest update took care of it. I know Microsoft had a big one this week. There are a lot of older versions of Windows 10 that will no longer be updated next month.

bit of a update, apparently whatever was wrong with the site on my end where pages either wouldn't load completely or not at all without refreshing/reloading at least four or five times just sorted itself out and the site is working normally for me again so yay? lol

What kind of issues?

out of curiosity, is anybody else having major issues trying to load up pages or post comments?

I've upgraded again the server to a newer version.
So if you notice something unusual in the next days, please report it here.

Indeed, El Captain is 10.11, so you can either update to at least High Sierra (10.13) or use Firefox in case you were using Safari or Chrome.

I’m using an older MacBook from before 2017, and I think I have OS X El Capitan on it.

What kind of device are you using?
On 1st October a root certificate was expiring on devices from 2017 and before, so if they were not updated they can't connect to sites that use Letsencrypt for HTTPS (like imcdb and millions of others).
For example Windows XP and MacOSX 10.12 or older are concerned.
If you can't update your system, you can try using Firefox (a not too-old version) which uses its own set of root certificates.
If you also have that on the main imcdb site, there you can still use the non-https version (as it is not automatically redirected).

Well, I also got it, but this only occurs on my laptop.

Am I the only one??
