Facebook connect taking me to a blank page

Please go into the Joomla Global Configuration and set Error Reproting to "Maximum" and disable GZip compression. Then, try to recreate the white page error. That will hopefully display a pretty PHP message that will help narrow things down.

If that doesn't, I'd recommend disabling your JFBConnect Profile and Open Graph plugins and try again. If that works, slowly enable each plugin and test again so until you narrow down what plugin (if any) is causing the problem. Let us know, and we can definitely help from there.

Also, try with a different Facebook account to make sure it's not something specific to that Facebook user.

Thanks,

Glad to hear that was solved by your developer. As for the error message is, I have no clue. The file throwing the error is /libraries/expose/core/core.php. That's not a part of JFBConnect or anything that we interface with. You'll need to find out what extension is adding the 'expose' library to your site and then incorrectly calling a function on it.

The message is just a notice, which isn't really a big deal (and easily hidden by changing your error reporting setting). If you're experiencing issues though, that notice could be part of the problem.
