 * Hello,
 * This is an error caused by the PHP version we do not support 5.4.45 anymore.
   
   Can you upgrade to at least 5.5.1 and see if that solves the issue for you?
 * Let us know, thank you!

   I can help you patch and fix this but I would also strongly recommend that you
   upgrade your PHP version as it is not supported anymore.
