 * I hope someone can help me urgently.
 * I upgraded Posts 2 Posts plugin from 1.6.2 to 1.6.3. As soon as I did this I 
   lost my site with the white screen of death appearing. Trying not to panic I 
   managed to revert to v1.6.2 and got the site back.
 * However, now when creating connections, the spinner spins eternally and the connection
   does not register.
 * Javascript error points to box.js on lines 188 and 313:
 * 188: ‘undefined’ is not an object (evaluating ‘this.options.connections’)
    313:‘
   undefined’ is not an object (evaluating ‘this.options.candidates’)
 * I am afraid to try upgrading again as the site is large and complex, but the 
   client relies on the connections to work and adds content daily.
 * What can I do?

 * Seems there was a conflict with WP3.9 as another plugin was also affected. I 
   reverted to WP3.8.3 and all is well.
 * May be worth investigating though.
