Invalid Token, plus backend error

There a few posts before about Invalid Token when trying to login user, but this one is a bit different.
Disabled cache, FB and other API's are correct.
This happens when user is logging in using existing username and password (not social buttons)
"INvalid Token Error"
Also, when trying to change option in backend, getting an "0 - Error" - attached.

I have an installation of JFB connect on another site, and it works fine,
the difference on this one is:
1. J2.5 instead of 3
2. download ID, just expired so was not able to run autotune.
- does this mean i can no longer use the component after support expires?
that's not good...

Any help much appreciated
handility.com is the domain - for login click on the drop down tab'

Invalid Token Error fixed.

Now the problem remains: cannot edit any settings in joomla backend (JFB component) - it always gives the Error attached in the original post.

0 - An error has occurred.
Table config not supported. File not found.

Cool!
Thanks for that suggestion, it worked.
Just in the interest of others encountering this, you need to uninstall component, clean cache and in my case run an sql table refresh or fix, otherwise, the component reinstalls using the same corrupt table (i think)...

What still happens now:
1. When I am in JFBC dashboard "Facebook Application information not found. Please run AutoTune to fetch your settings."
FB App is working correctly, so not sure why this still appears. I just want the autotune prompt to politely get off my back

2. Trying to run channel display (Social stream from FB page), signed up up as a new user using FB social connect,
selected that user in backend as author of channel, but the message i receive is:
"The selected user has not granted the "manage_pages" permission. Please have them login on the front-end of the site and accept the correct permission."
- I can't for the life of me find that variable anywhere, can you help? How to users grant permissions from front end?

Thanks Mel,

For some reason now, social buttons are inactive:
The sclogin module displays social buttons, but they cannot be clicked on, I tried with and without jquery (it seemed like a java thing), and with and without encryption and forcing ssl.
Any ideas?

Hi Alex, yes this seems to be the issue,
(this happened when i reinstalled JFB as part of another problem) - so I enabled JFB both system and user plugins etc...
and now the site just goes blank, I contacted server admins, they said it is a joomla issue not a server one, so I am a bit stuck...
why would this be happening? any clues?

I went through the forum and it seems like it's not a one off issue, has been happening to other users, mainly to do with missing php libraries.
(in my case it is not the J version, I am using the latest 2.5)

(I was not able to login to backend, so via FTP I renamed the component folder, now the site is back up but JFB is obviously not live - giving message attached)

What is the best way to try to address the issue?

Hi,
I re-installed (third time now), but still same result. Best way to explain this is here
it's a screencast, disabling, enabling, errors, etc...
Please help
