I got that last night as well on a totally different computer with different browser and OS. I'll email Hugo, hopefully he can straighten it out.
I have not been able to post photos for a couple of days now. Looks like you have finally filled up the site with Japanese advertisements and catalogues! Although I did notice that my Sharp scans are in PNG which I should have converted to JPG, maybe that was the straw that broke the camels back! I might update them when posting images is fixed as they are a bit slow to load anyway.
I just tried to upload a photo, but also got an error... Maybe a bit too many uploads after all? How many quettabytes is the server by now?
Walkman Archive would know, I have no info. The photos seem to trigger the errors. Unfortunately this type of forum needs photos for interactions.
There's some older discussions on some of these errors over on the XenForo Forum https://xenforo.com/community/threads/push-notification-failure-429-too-many-requests.220195/ I can barely read computerese but it sounds like there's too many requests outside of the forum trying to get in triggering the error. Besides AI, I wonder how many scammers are trying to get email address and other nuggets of info, clogging up the interwebs.
I can't post a screen shot of "A server error has occured" but AI says it has to do with CloudFlare and needs to be adjusted in the forum control panel.
It looks like we are able to upload pictures again if anyone was waiting for that. I also changed a few of my images in the Sharp Ads! post to jpg and they are much snappier now, in fact many of the pngs don't load at all, but the jpgs seem to work well. I might go back through some of my older posts and update any scans I have done. Luckily that is easy enough for me as I have not made that many posts!
I couldn't get in last night, something about the server being full. I wonder if the hacked accounts are injecting code somewhere and bloating the forum. I don't know enough about this kind of security.
