[Bug / Issue] Internal Server Error when "Enable Facebook Platform" set to yes.

[karlm]

I was tinkering around and went to inspect the registration page. Alas, I was confronted with an internal server error message and no form of input available. I disabled the twitter app (login & sign in) and it persisted. I then disabled the "Enable Facebook Platform" option and refreshed the registration page - it then showed the usual input forms.

Since then, I re-enabled the twitter login/sign-in and the registration page continued to operate as expected.

It might be something my side... but I thought I'd let you good folks know

Internal Server Error is probably the most generic error to ever exist in the history of computers. It doesn't even tell us what component caused the error. If you put your site into Debug Mode, does the output of the page change with that option enabled?

An internal error has occurred and the module cannot be displayed. Template: widget_register Controller: facebook Method: userIsLoggedIn Arguments: Array ( [0] => true ) Errors:
Array
(
[0] => Array
(
[0] => unexpected_error
[1] => Signed request has an invalid signature.
)

[1] => Array
(
[0] => exception_trace

(then a load of paths which I won't paste here)

The paths tell us where the error is happening. But it seems related to your other issue. We're probably going to need a support ticket and access to your server.

Not a problem with either - I'll create an admin access for you - do you want ACP & FTP access? Plesk?

[Wayne Luke]

AdminCP and FTP to start.
