Title: Stops working after a while Last modified: August 30, 2016 --- # Stops working after a while * Resolved [Jeremy Karlsson](https://wordpress.org/support/users/enjikaka/) * (@enjikaka) * [10 years, 7 months ago](https://wordpress.org/support/topic/stops-working-after-a-while/) * Hello, * Fighting EWWW on a Digital Ocean droplet is kinda hard. Me and a friend has had huge troubles getting EWWW to work. * After fiddlin’ around with permissions, groups and users I managed to get EWWW to work. Now, after a few days, EWWW has stopped working again without me doing anything. It says that “jpegtran, optipng, gifsicle” is missing. * Permissions on /ewww and all its binaries in the /wp-content directory: [http://i.imgur.com/aiCmfvx.png](http://i.imgur.com/aiCmfvx.png) *

Besides jpegtran and optipng should both bundle their own internal libraries for those anyway, but I figured it was worth a try. I wonder if it is something tricky with HHVM then. I’ve never tested HHVM, but I think other users have made it work. Seems like something is suppressing the output from the binary files, so let’s run one of them manually to see what happens. * Login to your server via SSH, and run this command: * `/home/websites/sverige.science/www/wp-content/ewww/optipng -v` * That should output the version, copyright info, and credits. * Thread Starter [Jeremy Karlsson](https://wordpress.org/support/users/enjikaka/) * (@enjikaka) * [10 years, 7 months ago](https://wordpress.org/support/topic/stops-working-after-a-while/#post-6588181) * [http://i.imgur.com/nANSkvH.png](http://i.imgur.com/nANSkvH.png) * Plugin Author [nosilver4u](https://wordpress.org/support/users/nosilver4u/) * (@nosilver4u) * [10 years, 7 months ago](https://wordpress.org/support/topic/stops-working-after-a-while/#post-6588182) * Perfect, so the binaries are there, and functional. Now to figure out why their output is being suppressed by HHVM. * Might be easiest if you could take a snapshot of your server, and transfer it to me.
