Content Hub troubleshooting guide

There may be instances when you find that Content Hub is not working as expected. In these cases, you must troubleshoot your installation.

Content Hub diagnostic module

The Content Hub diagnostic module, when enabled, provides you with information that ensures your installation has the proper basic configuration.

The Content Hub diagnostic module is included in the normal installation. After the module is enabled, a new section will display in Reports > Status report.


If this report section is green, your Content Hub installation is configured correctly. If there are potential issues with your installation, this report section will provide the corrections that must be made to ensure successful product use, and can include module updates or patches.

Content Hub history logs

Content Hub tracks information about the service by using the history API endpoint. This information can help you troubleshoot issues, and you can review the history logs for Content Hub. For more information, see Using the Acquia Content Hub API.

Composer and Drupal 7

We do not recommend using Composer to download Drupal 7 modules. Downloading the tarball for Drupal 7 modules is the recommended method.

Fatal error when installing Composer dependencies with Drush

Composer Manager depends on the Composer Drush extension to install the Composer tool.

Possible cause: Outdated Composer

If you run drush composer-manager commands and see errors like the following, try updating your Composer Drush extension.

Could not load package...
Could not parse version constraint...

To resolve this issue, delete the current version of the Composer Drush extension and reinstall it by running the following commands ( 8.x is the correct version):

rm -Rf ~/.drush/composer
drush dl composer-8.x

Then run the following command inside of your Drupal installation:

drush composer-manager install

Unable to verify certificate

When you use both Composer Manager and the Composer tool directly, the PHP version that ships with Acquia Dev Desktop may be unable to validate the SSL certificate for GitHub and Packagist. An error similar to the following may display:

The "" file could not be
downloaded: SSL operation failed with code 1. OpenSSL Error messages:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify
Failed to enable crypto
failed to open stream: operation failed


Do not use the PHP shipped with Acquia Dev Desktop when running drush composer-manager. Use the Composer command line tool directly.

If you still have fatal errors when running drush composer-manager install, you can use Composer directly to install the required third party dependencies. From your docroot directory, run the following commands replacing [SITE-DIR] with your website’s directory, typically default.

cd sites/[SITE-DIR]/files/composer
curl -sS | php
php composer.phar install --no-dev

AJAX errors with Views exposed filters

Views exposed filters may cause AJAX errors. Remedy this by either installing the latest -dev release of the Views module or by using this patch.
