If I try to log in to my Facebook account from any laptop/browser I can`t reach my account. I write my correct e-mail and password, I don`t receive any message something is wrong but the moment I push log in/enter the password field becomes blank and nothing happens. From my Samsung Galaxy S5 I can open my Facebook account but I can not reach any settings/activity log/security/Security Inbox, etc. The second I try I get logged out with the message "Facebook authentication failed". So I can not control anything, not reach anything. If I go to settings I get thrown out. If I try reach Facebook trough the help/report I need to log in again and I can`t bc nothing happens. If I try to report my profile I can`t. My friends have also tried. What do I do to fix this? I have deleted caches and data, deleted the app, reinstalled. Deleted other apps connected to Facebook. Nothing helps. If I search for my profile by e-mail or phone I can`t find it, but I can find it with my name. When I try to go further and open it it just disappears. My friend list can see my profile as normal. What to do? Please help!
