Error after upgrading to Jooma 3

That error shouldn't be preventing the site to load. Strict Standards warnings are usually just notifications that something in the code isn't 100% perfect, however, it shouldn't cause the page to break. Generally only "Fatal Errors" can do that.

To fix the issue, I'd recommend:
* Editing the configuration.php file for your site
* Look for the following line:

public $error_reporting = 'development';

* Change it to:

public $error_reporting = 'none';

That should no longer display that message and you should be able to access the admin area.

Then, upgrade to JFBConnect 6.1.2, the latest version, which does not have that problem in the code.

I hope that helps, but if you need anything else, please let me know.

Thanks,

No problem. Glad to help. I see you have another issue that I'll be responding to in a moment as well.

Thanks,
