 * Hi,
 * After activation I click on BigBlueButton under the settings menu, at the end
   of the page I find:
    Fatal error: Class ‘SimpleXMLElement’ not found in /home/
   admin/data/www/online.repka24.ru/wp-content/plugins/bigbluebutton/php/bbb_api.
   php on line 45
 * Doesn’t work.

 * That can be either a connectivity problem between your wordpress server and the
   BigBlueButton server you are using or directly a problem on the BigBlueButton
   server response.
 * First try using the settings that come by default. If that doesn’t work then 
   is the first option. If you are on linux and you have access to the terminal 
   do:
 * wget -q -O- [http://test-install.blindsidenetworks.com/bigbluebutton/api/](http://test-install.blindsidenetworks.com/bigbluebutton/api/)
 * You should get a xml response like this
 * <response>
    <returncode>SUCCESS</returncode> <version>0.81</version> </response
   >
 * Most likely is that it won’t work. If it doesn’t then you have the diagnosis.
   Now you need to find the solution (to the connectivity problem). If it works 
   let us know.
 * Good luck!

 * For those experiencing this problem, the solution is to install the php5-simplexml
   library in the server.
