We upgraded our PHP version on our server and Joomdle couldn't connect to Moodle. In the "Systems Check" tab of Joomdle, "Joomdle Web Services" said "Received empty response from Moodle". Since no settings changed, it was unlikely to be any of the usual issues with bad URLs, etc.
This was throwing a couple of errors in our Apache server log:
Code:
PHP Warning: file_get_contents(http://oursite.com/moodle/webservice/xmlrpc/server.php?wstoken=xxxx) [<a href='function.file-get-contents'>function.file-get-contents</a>]: failed to open stream: HTTP request failed! HTTP/1.1 500 Internal Server Error\r, referer: http://oursite.com/ in /home/user/public_html/administrator/components/com_joomdle/helpers/content.php on line 137, referer: http://oursite.com/
PHP Fatal error: Class 'DOMDocument' not found in /home/user/public_html/moodle/lib/zend/Zend/XmlRpc/Generator/DomDocument.php on line 98
The issue was that our distro of PHP didn't include the PHP-XML module that handles "DOMDocument". Once installed, everything started working again.
