Updated yesterday and minification was turned on. I tried to turn it off and it wouldn't switch off.
Unfortunately minification screws up my website so I have to turn it off (haven't had time to go through each file and fix them). Lucky I had a backup of the previous version so I was able to revert.
On an extra note when I deactivated the plugin it didn't cleanup it's mess and the site was totally broken.
This happened on both my sites which both have the same issues with minification.
