FB connect not working, and profiles page broken in backend

As title says, the FB connect isn't working, and when I try to go to the social profiles ( after installing them for jomsocial ) the page appears as broken HTML code, and I cannot do anything.

I have no idea what is causing the 2 problems, and the facebook connect one seems complicated- on one computer, the window opens then closes instantly when clicked on, on another it stays open but it still doesn't work in later steps. I included a screenshot of the backend problem of the profiles.

Hello Alex, thanks for the reply.

I switched my hello me module with your facebook connect module for guests, and also ran the auto tune for errors ( it found a few ) and updated my versions.

Fixed quite a lot!

I have one problem remaining; when people use the connect with facebook feature, everything works, but at the last step, I'm guessing it's supposed to get them to a page that says thanks for connecting with facebook, it sends them to a error 500 page ( my page is in french ):

Error: 500 - Affichage introuvable [name, type, prefix] : jfbconnect, html, jfbconnectView

You may not be able to visit this page because of:

an out-of-date bookmark/favourite
a search engine that has an out-of-date listing for this site
a mistyped address
you have no access to this page
The requested resource was not found.
An error has occurred while processing your request.

But it does send them an e-mail saying it worked, and their account really works after.

Any clues, any ways to fix this?

Thank you.
