The images have not been processed and come from a variety of sources including my own camera so I’m a bit of a loss as to what is happening? * > jpegtran is missing > Image Size: 155.45 kB jpegtran is missing * Please advise * [https://wordpress.org/plugins/ewww-image-optimizer/](https://wordpress.org/plugins/ewww-image-optimizer/) Viewing 15 replies - 1 through 15 (of 18 total) 1 [2](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/page/2/?output_format=md) [→](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/page/2/?output_format=md) * Plugin Author [nosilver4u](https://wordpress.org/support/users/nosilver4u/) * (@nosilver4u) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178476) * the jpegtran error has nothing to do with your images, and everything to do with the server your site runs from. Are these two WP installs on the same webhost? * Thread Starter [Dave](https://wordpress.org/support/users/tlwh/) * (@tlwh) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178479) * Yes they are on different servers. * I just activated the plugin on another install from the first server where I noticed the problem. * It doesn’t give an error but just says “no savings” on existing photos. * I uploaded a new photo and it processed it with no errors. * Bit strange it’s working on one install on the same server as another where it’s not which is a new install. BTW another optimiser works. * Plugin Author [nosilver4u](https://wordpress.org/support/users/nosilver4u/) * (@nosilver4u) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178486) * Please post the plugin status and debugging information from both the working install and the non-working. * [Joel Usina](https://wordpress.org/support/users/jmusina/) * (@jmusina) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178507) * Greetings. * I just installed and ran the plugin with the same error. * I host with WPEngine. * Recommendation? * Plugin Author [nosilver4u](https://wordpress.org/support/users/nosilver4u/) * (@nosilver4u) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178508) * [@jmusina](https://wordpress.org/support/users/jmusina/), you should normally start your own thread. That said, WPEngine does not allow the regular EWWW IO plugin on their sites. You can only use it with a cloud API key installed, and you must use the cloud-only version of the plugin, or they will deactivate it: [https://wordpress.org/plugins/ewww-image-optimizer-cloud/](https://wordpress.org/plugins/ewww-image-optimizer-cloud/) * [Joel Usina](https://wordpress.org/support/users/jmusina/) * (@jmusina) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178510) * Cool. * I’ll start a new thread next time.

The not working one has exec() disabled. Is it not throwing an error about that on the plugins or EWWW settings page? * Plugin Author [nosilver4u](https://wordpress.org/support/users/nosilver4u/) * (@nosilver4u) * [10 years, 11 months ago](https://wordpress.org/support/topic/jpegtran-missing-cannot-optimise/#post-6178544) * nevermind, I already know the answer is NO.

Bottomline, those two sites do not have the same php config.
