I solved this problem by adding a line of code to the wp-config.php file. Just after the lines below add this line:
define( ‘JETPACK_CLIENT__HTTPS’, ‘NEVER’ );
The final should look like this:
* @package WordPress
*/
define( ‘JETPACK_CLIENT__HTTPS’, ‘NEVER’ );
// ** My SQL…
That solved any issues. I can’t promise it won’t cause another, but for now, so far so good.
I tried to use the debugger, but it won’t respond to the “contact Jetpack support” link. Does nothing. The status bar indicates that the link is, “Go to # on this page.” I tried several times.
I’m getting the same thing, but I have other WP installations with Jetpack on the same server that don’t get the error. Seems odd that it’s the server randomly letting it work for some sites and not others.
