Internal server error

My blog was running fine until today when i clicked on the jetpack. It took me to wordpress.com and i authorized it to connect jetpack. Right after that i could no longer login. I get error ‘Internal Server error’
‘Additionally, a 500 Internal Server Error error was encountered while trying to use an ErrorDocument to handle the request.’

the site itself is still there and showing up just fine, i just cannot login.
