Hi Support Team,  
  
I recently had a project which failed to start. Any time I pressed the ‘Queue Build’ button I got the following error: “An unexpected error occured whilst performing an AJAX request with the web server. Please try again.” Trying again did not solve the problem…  
  
When I recognized that “Queue a build immediately” worked I found that a variable containing curly brackets in its description was the problem. The description contained the text {VersionNumber}. Changing the curly brackets to square ones solved the problem.  
  
Please consider this to fix.  
  
Best regards  
Michael
