aha ... Sorry, this issue is a bit funny ... The issue stems from your server being SunOS.
For some very strange reason, SunOS does not allow using GLOB_BRACE in PHP.
http://php.net/manual/en/function.glob.php
Note: The GLOB_BRACE flag is not available on some non GNU systems, like Solaris.
We rely on glob_brace to get first image in the logo folder:
$images = glob($dir.'/*.{jpg,gif,jpeg,png,svg}', GLOB_BRACE|GLOB_NOSORT);
This fails on your system. In fact, we already have a half-workaround in pending release:
$images = strtolower(PHP_OS) == 'sunos' ? glob($dir.'/*.[jJ][pP][gG]', GLOB_NOSORT) : glob($dir.'/*.{jpg,gif,jpeg,png,svg}', GLOB_BRACE|GLOB_NOSORT);
However, it's still not perfect, because it would only get the first JPG file on Sun OS.
I will look into it tomorrow and see if I can come up with a solution.
