Like title says; I've cleared cache, cleared cookies, logged out and in, reset computer, reset router... nothing works. DM can access it, but I can't whatsoever. 

Are you running any ad/popup blockers, browser extensions, or a VPN? One of those might be interfering with DDB.

Nope- I even turned off my firewall to check, the only thing was the extension for Roll20 to connect to DnD Beyond but I deactivated it to check

Have you tried a different browser or device?

Yep, doesn't work on any browser and using a separate device makes it pointless since I'm using my PC so I can use my sheet to roll in Roll20.

It’s probably the Beyond20 extension that’s causing your problem. Try disabling it.

Same issue here. I don't have any extensions but still cant load anything character related
