 Technically the file load-style.php has a bug, however it is a scenario
 based-bug so it rarely occurred. Not going in to so much details of PHP
 the problem is with the variable $out concatenation of "$contents" used in
 the foreach loop, i.e., O(n) complexity issue - the allocated buffer is
 exhausted assigned by PHP during the single http request execution.

 The better and optimized way is:

 move the "header" just the above "foreach ( $load as $handle )" loop
 statement.
 remove "$out" , i.e., echo $content rather concatenating into $out.

 I had this issue during installing app on my local machine, and solved it
 happily by doing changes that way.
