Title: Redirection to conversion script is not enabled Last modified: July 1, 2019 --- # Redirection to conversion script is not enabled * Resolved [Mike](https://wordpress.org/support/users/mixar/) * (@mixar) * [6 years, 11 months ago](https://wordpress.org/support/topic/redirection-to-conversion-script-is-not-enabled/) * When we updated from 0.14.4 to 0.14.21 all images stops to show on nginx (method 1 settings). When we try to open any image from browser, we get message: Validation failed for settings: Redirection to conversion script is not enabled So we moved back to 0.14.4 which has security flaws:( Viewing 11 replies - 1 through 11 (of 11 total) * Plugin Author [rosell.dk](https://wordpress.org/support/users/roselldk/) * (@roselldk) * [6 years, 10 months ago](https://wordpress.org/support/topic/redirection-to-conversion-script-is-not-enabled/#post-11789536) * Ah. The conversion script only allows to run when redirection to conversion script is enabled. I will disable that check for Nginx. Until then, simply check the“ Enable redirection to converter?” checkbox in the “Redirection rules” section * Plugin Author [rosell.dk](https://wordpress.org/support/users/roselldk/) * (@roselldk) * [6 years, 10 months ago](https://wordpress.org/support/topic/redirection-to-conversion-script-is-not-enabled/#post-11789574) * This has been fixed in [the development branch](https://github.com/rosell-dk/webp-express/issues/309).

Trying to pull up the logo PNG directly, I get this message `Validation failed for settings: Redirection to conversion script is not enabled` which led me to this thread. I don’t see any WebP Express settings related to Redirection or “Enable redirection to converter”. Any suggestions on how to deal with this? Thank you. * [gmw0113](https://wordpress.org/support/users/gmw0113/) * (@gmw0113) * [6 years, 6 months ago](https://wordpress.org/support/topic/redirection-to-conversion-script-is-not-enabled/#post-12210145) * Same issue here. * [shorelinechrism](https://wordpress.org/support/users/shorelinechrism/) * (@shorelinechrism) * [6 years, 6 months ago](https://wordpress.org/support/topic/redirection-to-conversion-script-is-not-enabled/#post-12225552) * We are running into this issue on WPEngine. We gave support the Nginx rules and followed the settings on the docs and the webp functionality is working correctly, but any non-webp files that might be served in CSS files is resulting in an error: * `Validation failed for settings: Redirection to conversion script is not enabled` * It would be helpful if anyone figured out a way to combat this on WPEngine, please. * [shorelinechrism](https://wordpress.org/support/users/shorelinechrism/) * (@shorelinechrism) * [6 years, 6 months ago](https://wordpress.org/support/topic/redirection-to-conversion-script-is-not-enabled/#post-12225622) * Ok, everyone. If you are on WPEngine, the WebP Express documentation they had was a little outdated. Due to changes in the plugin code, you cannot use “CDN Friendly” mode if you want your WPEngine site on Nginx to serve non-webp images( like those that might be referenced in CSS files) without an error message. * To make it work on WPEngine, follow the same setup and send Nginx rules to support to add to your config, but then use “Varied image responses” mode instead. After you change the mode there will be a “Redirection rules” section now on the settings page. Make sure that “Enable redirection to converter” is checked off. Clear your cache and it should work.
