Hello. Had login problems too and found a working solution. Problem: The problem where, that i couldn't login to the FONV and the FO3 nexus. The Oblivion Nexus, the forum and NMM worked and still do. Solution: Login works for me only on the first/index page. if loggin in on a another page, nothing happens. No error message at all. Same with iE and Chrome (SRware iron). When accessing a mods page that needs me to be logged in, i can login on the shown page, but need to return to the index page to be really logged in. Copying and pasting the mods url, to return to the mods page immediatly, shows i'm logged out again. it's not really annoying but sure not user friendly. But i can find the mod easily again by copying the mods name from the login page and using the search function to ensure i'm still logged in when returning to the mods page.
