I installed and activated the WooCommerce Paypal Payments plugin and confirmed that it is working perfectly fine with our SiteGround Optimizer. I was able to enable/disable the CSS and JavaScript minifications just fine and did not encounter any errors. This leads me to believe that the issue is most likely related to your application. * If you are using any additional plugins that offer similar minification features it is recommended to disable them. Make sure that your WordPress application and all plugins are updated to the latest available release. You can also try reinstalling the SiteGround Optimizer and see if this would resolve the issue. * Best regards, Dimo * Thread Starter [Leandro](https://wordpress.org/support/users/leandroprz/) * (@leandroprz) * [4 years, 1 month ago](https://wordpress.org/support/topic/cant-enable-css-javascript-minification/#post-15544781) * I’m not using a second cache plugin. * I disabled the PayPal plugin on my site and I was able to make SiteGround Optimizer work just fine. Maybe there’s something else conflicting.
