Hello,
FB Login...with your FB account has to be made or edited FP application on developers.facebook.com.
Misspelling...that is easy to edit in Photoshop.
With upload picture, might be a problem. If I am not wrong, you are using old version of Joomla, might be that your hosting company has new version of php and something went wrong.
Also, with upload problem, can be million other issues, I have to look at it.
Waiting for your reply,
MIlos
