At times, WordPress to Buffer Pro may not be able to send your status to Buffer through the Buffer API.

Before opening a support request with us, please ensure you’ve completed the following steps:

  1. Enable Logging.  This can be done via WordPress Administration > WP to Buffer Pro > Settings > Enable Logging.
  2. Disable WP-Cron.  This can be done via WordPress Administration > WP to Buffer Pro > Settings > Use WP Cron?
  3. Review the logs of the failed Post.  This can be done by editing your Page, Post or Custom Post Type and making a note of any error messages that appear in the Log window.  If the Buffer: Response provides a meaningful error message, take a moment to review that and act as necessary.  For example, if the error states that your Buffer queue is full, or that the status message is similar to the previous message, then you’ll need to make changes.
    WordPress to Buffer Pro: Logging

When sending your support request, be sure to include:

  1. An Export of your Plugin Settings (WP to Buffer Pro > Import/Export > Export)
  2. An Export of your Plugin Log (Step 3 > Export Log)
  3. A copy of any on screen errors you see whilst trying to publish a Post to Buffer.

Please note: If we receive a support request that does not demonstrate all of the above items have been completed, we will ask that you complete them.  On average, we can resolve tickets 85% faster this way.

Common Issues

Buffer API Error: 400 Bad Request. Invalid image url parameter supplied

Buffer doesn’t accept image URLs with accented / special characters in the image filename.  You can install the Media File Renamer Plugin, which will automatically remove these special characters when you upload image(s) to WordPress.

Buffer will then accept the image you are trying to include with your status update, and no error will be returned.

Featured Image setting is not honored

Since December 18th, 2017, Facebook require that you verify domain name ownership when using what Buffer call “Link attachment customizations” (i.e. specifying a different image than the Featured Image for a Page, Post or Custom Post Type).

Please refer to Buffer’s and Facebook’s steps to verify your domain.

Featured Image does not display on shared Posts when set to use OpenGraph Settings

  1. Ensure that you have a compatible SEO Plugin installed, per the Use OpenGraph Settings section in the Featured Image Settings Documentation
  2. If you are using the Post Immediately option on a status, consider using the Custom Time option, and setting it to post 2 – 3 minutes after the Post publication.  This allows third party caching plugins, such as W3 Total Cache, sufficient time to build the published Post for Buffer (and the social networks) to read the valid OpenGraph data.
