site hacked - struggling to restore - fbconnect message appearing

Sorry to hear about your troubles. Not very good about the host to provide that stuff, obviously

If the files are in those locations, the best guess I can have for why they can't be read is that the permissions are wrong for them, or the operating system owner/user for those files isn't correct. It looks like the following file is there: public_html/components/com_jfbconnect/libraries/facebook.php. I'd recommend looking at the permissions and owner of that file and seeing if the usermap.php or config.php files (or the whole /administrator/components/com_jfbconnect directory) has different settings. If so, try to correct them and see if that helps.

Hopefully that helps, but if not, let us know. Your subscriptions a bit out of date, but we have a soft-spot for crashed sites..

Good luck,
Alex
