 * Thanks for the report! The first thing to check is whether any other plugins 
   on your site may have a conflict. Please check our Known Issues list here:
    [http://jetpack.com/support/getting-started-with-jetpack/troubleshooting-tips/](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.
 * If the issue persists after that, could you provide me with a link to your site
   so I can take a look?

 * Hi Jay! I had a look at your site and Jetpack seems to be properly connected 
   at the moment. Were you able to resolve this issue? If not, could you let me 
   know where the error appears? Thanks!

 * I was not able to resolve it. I get the error when I click on Jetpack on the 
   right side of my wordpress dashboard. I click Jetpack and it takes me to the 
   Jetpack dashboard and it has that error at the top of the page. It seems to be
   displaying correctly and not affecting anything that I can see,
    Thanks

 * Could you try temporarily disabling all of your plugins? Then, see if the issue
   persists. Please let me know how that works, and we’ll go from there!

 * It went away when I disabled Skimlinks plugin and came back when I enabled it.

 * Thanks for the update! Could you try contacting the author of the Skimlinks plugin,
   to report this issue? They should be able to look into this further for you! 
   Please let me know how that goes, and don’t hesitate to ask if you have any other
   questions in the meantime.
