I have spend about 6 months now not being able to type in chat or mail, the game was fine before. Now it lags and takes me about 10 minutes to write 5 words. Nothing I tried works, clear cache, refreshing, re-logging, changing browser, the pc and internet are working fine, this is the only site that has this issue .. I would really like to be able to reply to mails at least. 

UPDATE: I could reply if I would be let to, apparently when starting a new reply does not work, my typing isn't registered on the page, so here I am, editing this...

As for the initial in game bug, I usually play on edge(operating on win 8), I have tried on chrome, none of them let me type. I think is as permanent as can get since it lasts for months now. I cannot follow the guideline you have provided, there aren't any specific actions other than not being able to type in brotherhood chat or mail, it is a constant issue it is not provoked by something specific. 

Apologies for the atrocious English, it is not my first language.
