 * When logging in WordPress, I see this line on the login page:
 * Warning: Attempt to modify property of non-object in wp-content/plugins/jetpack/
   sync/class.jetpack-sync-module-users.php on line 67
 * Never modified the plugin. Don’t see anything unusual in line 67.
 * Thanks for any help.

 * Hi there! The first thing to check is whether any other plugins on your site 
   may have a conflict. Please check our [Known Issues list](http://jetpack.com/support/getting-started-with-jetpack/troubleshooting-tips/).
 * You can also try to deactivate all plugins on your site, and see if that resolves
   the issue. If it does, then activate them one at a time to determine which is
   causing the conflict.
 * If that doesn’t help, please rule out a theme conflict by temporarily changing
   your site’s theme to a default theme (such as Twenty Sixteen) and trying again.
 * Please let me know how that works for you, and we can go from there!

 * OMG. Sometimes simple does the trick … and we don’t think about it. <Kicking 
   myself> I simply turned off Jetpack. Saw no error. Turned it back on. Still no
   error. Weird! Thank you!!

 * I’m glad to hear that did the trick! Please let us know if you experience any
   further trouble.
