Each time I try and upload anything it says something went wrong, any ideas of what could be happening?

Viewing any submission results in an Error 500. Uploading any new submission also results in an Error 500. This has been going on since August 27th (8 days ago)

Nobody can join/login/upload (including myself), the devs/admins/whoevers-"running"-this-site haven't been responding to these posts for years, "Commissions Feedback" is overrun with spam/bots, and the (I presume) official twitter account for FurryNetwork hasn't been updated since 2020...

Not sure whats going on but I have been having issues uploading my illustrations to FN. At first it was hitting 100% and just staying black, if i refresh page, the upload vanishes. Today when i tried to test upload, it said something went wrong. 

I can not for the life of me find the section of this website that lets me add information to my about section. It would make the most sense for this to be in the "Edit Profile" section of this site, but all that has is Avatar, Banner, Name, Privacy, Profile, and Homepage. If one of those are how you make an about, it should say that it's the about section on that tab.

Technically I can't enter my own tags and if I try to put enter it leads to another slot beneath tag and it's so much harder on my phone

Let it be possible to have (on the main site) not just @username but @UserName, for example, I mean, with any specified case. And to alter the case of letters of already existing username. Therefore, a username won't be changed in general, but will allow to express some aspects of user's personality, and could be more recognizable to other members of the community.

Forsome reason i cannot upload my art it gets to 99% and then freezes is there a way to fix it

I can't login I know my password and username I have it written down. It says invalid password username combination and I've tried resetting it and it just keeps saying enter a valid password and it does not tell me what is considered a valid password.
