I just got a question of php version on Dev Desktop.
I had issue to upgrade php5.6 on my Dev Desktop. Trying to fix it, I have reinstalled the latest version DevDesktop on my Windows Machine. It doesn't load any JS libraries even if I drush cc all. Anyway it works after I re-pulled db and code on php5.5.33.
Once I switch to 5.6.19, the site stop working. I also replaced the latest php_apcu.dll in ext folder, still doesn't work.
I have attached the log files for you to check.
