Hi there  
  
I’m tring to install mautic on a host but It fires this error  
  
 ![](http://imgur.com/a/XppAR)  
  
I tested with version 1.3.1, 1.3.0 and 1.2.1. All of the are missing the file bootstrap.php.cache in the folder app  
  
ps: I didn’t install newer versions cause updating my host PHP may brake some sites
