That’s odd. Sorry for the trouble!
Could you add the following to your site’s wp-config.php file?
define('WP_DEBUG', true);
if ( WP_DEBUG ) {
@error_reporting( E_ALL );
@ini_set( 'log_errors', true );
@ini_set( 'log_errors_max_len', '0' );
define( 'WP_DEBUG_LOG', true );
define('WP_DEBUG_DISPLAY', false);
define( 'CONCATENATE_SCRIPTS', false );
define( 'SAVEQUERIES', true );
}
Once you’ve done so, try to trigger the error again, and then check the wp-content/debug.log file for errors. You can paste the results here. You can then replace define('WP_DEBUG', true); by define('WP_DEBUG', false); in the code above.
Thanks!

Here is the line in the log file:
[07-Sep-2016 14:50:58 UTC] PHP Notice: Undefined property: stdClass::$theme in /home/a11y6lobal/public_html/wp-admin/includes/class-wp-upgrader.php on line 2950

That error doesn’t seem related to Jetpack. Could you try to switch to one of the default themes, like Twenty Fifteen, for a few minutes?
If that doesn’t help, could you try to deactivate each one of your plugins, one at a time, and let me know if you find a conflicting plugin?

Jeremy, this is a live site. Switching the theme and reconfiguring the current one will be too time consuming unless there is an easy way to do that. I can try disabling some plugins and see if that helps. I suspected at first Wordfence and disabled it when I first experienced the problem but that did not make a difference.
Is it possible that the file in question may be corrupt? They have not upgraded to the latest WordPress either.
I will play with the plugins and report back.

Success! I have identified the plugin that triggers the error. I will write to them to inquire. It is called Multilanguage Pro by BestWebSoft to handle displaying content in different languages.
Thanks for the pointer, I will mark this thread resolved as far as JetPack is concerned.
