Jetpack 3.0.1 To Fix General 500 Error With Spelling and Grammar Module

Soon after the release of Jetpack 3.0, users reported problems with the spell check module which utilizes the After The Deadline service. In Jetpack 3.0, when users proofread a post, they are greeted with a General 500 error. The error also shows up if you’ve configured it to automatically proofread a post before publishing.

The Jetpack team is aware of the issue and is working on a point release that will be available soon. Until then, if you want to apply the fix before the release, navigate to jetpack / modules / after-the-deadline / proxy.php and replace the Proxy.php file with this one. The error has to do with AtD calling an undefined function in proxy.php. A detailed explanation can be viewed via the following ticket on Github.

The Jetpack development team has done a fantastic job fixing problems discovered soon after a release. Earlier this year, the team rapidly put together an update shortly after the release of 2.9 to fix a bug with the spell checking module that prevented posts from being published. Only eight days separated the release of 2.9 from 2.9.1.


Jetpack 3.0.1 is available for download. You should see an upgrade notice soon in your dashboard. This release fixes the spelling and grammar module and contains several other bug fixes.

  1. Thank you, Jeff. Glad to hear there’s a fix for the issue coming out soon. I ran into the issue yesterday with Jetpack 3.0 when the General 500 error message wouldn’t allow me to publish a post. I found a workaround by using Quick Edit to change the status from “Draft” to “Published.”

  2. I just installed 3.0.1 and got this error, anyone know what it is?? Warning: require_once(/home/nowtheen/public_html/blog/wp-content/plugins/jetpack/functions.twitter-cards.php) [function.require-once]: failed to open stream: No such file or directory in /home/nowtheen/public_html/blog/wp-content/plugins/jetpack/class.jetpack.php on line 748

    I dont even have something called “twitter-cards” on my site, why would it be looking for it?

  3. Sorry, here is the rest of the error message – Fatal error: require_once() [function.require]: Failed opening required ‘/home/nowtheen/public_html/blog/wp-content/plugins/jetpack/functions.twitter-cards.php’ (include_path=’.:/usr/lib/php:/usr/local/lib/php:/home/nowtheen/php’) in /home/nowtheen/public_html/blog/wp-content/plugins/jetpack/class.jetpack.php on line 748
