  Hello :) Are you able to reproduce the issue when installing a new instance of WordPress under a test account? If not, the issue might be related to a third-party WordPress plugin. Are you using any third-party plugins on this WordPress installation? Thank you.

  I'm having the same problem except for the fact that I did not update anything; i got a domain via my school so i don't have many rights. I only use 1 domain and 1 database via phpmyadmin. Everything worked just fine until at some point I got this: Headers and client library minor version mismatch. Headers:50535 Library:100026 All help is welcome!

  Hey mate, how you doing? well I had this issue with WordPress version 4.5 but then I updated WordPress to the latest version 4.6 and issue resolved automatically, please try to update your WordPress version if you are using WordPress CMS, thank you.

  You may need to report this issue to your web hosting provider for additional assistance, as that's not typically an error message you can address without root access to the server. Thank you.
