I’m running WordPress on AppEngine and have everything working fine (followed the GAE install instructions) except I can’t insert an image into a post. I’ve installed the GAE WP plugin and have the cloud storage set up properly (which I know because the upload actually works and I can see the uploads when I go to Media > Library in the left nav in WP.

Here’s the error’s I have in the logs for wp-admin/async-upload.php:

  1. This isn’t the optimal solution, but as a temporary workaround I’ve been able to solve the problem by suppressing errors in /includes/post.php. Basically the AJAX call was getting a bunch of errors with the data and didn’t know what to do with it so I just stuck error_reporting(0); at the top of the file.

  2. You could also get rid of the messages by adding “application_readable: true” to the following mapping in your app.yaml

    - url: /(.*.(ico|jpg|png|gif))$
  static_files: wordpress/1
  upload: wordpress/.*.(ico|jpg|png|gif)$
