Array Key Errors

Sorry for the delayed response. We are investigating the issue, but my guess is that you're not having any functional issues caused by this (missing avatars, improper logins, etc). The message above is simply a PHP warning message that a call we're making isn't 100% correct. However, it's not an error or something that's critical for functionality.

What I'd recommend is going to the Global Configuration area in Joomla and setting Error Reporting to "None". That will hide all PHP notices and warnings, which is the recommended configuration option for production sites. Showing warnings is useful on development sites so we can narrow down and eliminate these types of issues, but you don't want them shown on production sites for many reasons.

I hope that helps explain. Of course, if you feel there are any functionality issues that aren't working on your site, just let us know. Otherwise, we'll try to get a fix for the in the next release.

Thanks,
Alex

If you're still seeing that message with Error Reporting turned off, it means either your server is forcing error reporting to always be on or another extension is. Either way isn't good as those messages shouldn't display on a production / live site.

We've investigated the issue and found the cause. The problem only occurs when a user has authenticated with LinkedIn (or possibly Google+) but is currently logged in using a different social network.. or Joomla credentials. The SCLogin module is trying to fetch the user's avatar from LinkedIn, but the authentication token isn't valid, since the user isn't logged in that way.

We have a fix for the next release that will properly check for an auth token and hide that message. If you want the code update, we can gladly provide it to you as it's just a few lines to change.

Thanks for the report, and sorry for the inconvenience,
Alex
