XF 1.0 Users can't login

[C-Sea.org]

Currently no users can log in when trying to sign in to my site. I am only able to get in from a desktop while using the 'keep me signed in' checkbox. But that doesn't work for everyone. I also cannot log in to the xenforo admin section. It seems like it logs me out as soon as I log in.

Are you really running 1.0? That's not really a supported version any longer.

Have you made server changes recently? Setup something like CloudFlare or another reverse proxy?
