ERROR 500

Hi Sebastiano,
I need more informations about your issue. Could you post here the error messages in your Apache error.log?

Tnx

As you can see in the following var dump, the Libraries API libraries_load() doesn't load the php files: the attribute 'loaded' is FALSE.

array ( 'name' => 'Iubenda PHP class', 'vendor url' => 'https://www.iubenda.com', 'download url' => 'http://simon.s3.iubenda.com/iubenda-cookie-class/iubenda-cookie-class.zip', 'version arguments' => array ( 'file' => 'iubenda.class.php', 'pattern' => '@version:\\s+([0-9a-zA-Z\\.-]+)@', 'lines' => 5, ), 'files' => array ( 'php' => array ( 'iubenda.class.php' => array ( ), 'simple_html_dom.php' => array ( ), ), ), 'info type' => 'module', 'module' => 'iubenda_integration', 'machine name' => 'iubenda-cookie-class', 'download file url' => '', 'path' => '', 'library path' => false, 'version callback' => 'libraries_get_version', 'dependencies' => array ( ), 'versions' => array ( ), 'integration files' => array ( ), 'callbacks' => array ( 'info' => array ( 0 => 'libraries_prepare_files', ), 'pre-detect' => array ( ), 'post-detect' => array ( 0 => 'libraries_detect_dependencies', ), 'pre-dependencies-load' => array ( ), 'pre-load' => array ( ), 'post-load' => array ( ), ), 'post-load integration files' => false, 'installed' => false, 'error' => 'not found', 'error message' => 'The Iubenda PHP class library could not be found.', 'loaded' => false, )

I'm debugging in your environments.
Stay tuned for further news.

In this patch I updated the installation guide in README.txt because the Iubenda PHP Class dir name was wrong. Than I added a check before using Page class to prevent WSOD.

I'll push this patch in 7.x-2.0-dev release ASAP.
