After updating to RW 6.2.4 I cannot preview or save my site. I receive the following message:  
Exception while exporting site \*\* +[NSString stringWithCString:encoding:]: NULL cString  
Any help will be greatly appreciated

Absolutely right. Nothing to do with the RW update. OS X 10.10.5 is the culprit!  
Thank you!
