Webp format image to upload in PS 1.7

[Ornot]

Thanks to @vekia

Prestashop Version 1.7.5.2

Linux dedicated server.

PHP 7.2

 

I try the solution of Vekia here, three days ago

https://mypresta.eu/developer/webp-in-prestashop-files-manager.html

and It worked.

But today, unfortunately, It do not work 

and I don't know why.

possible that PS BO generate code? like .htaccess

 

Now, I clear cache in ftp and cache from navigator.

and I regenerate htaccess file. Not work

Best way is to use module, that auto changing format to webp in my opinion. Instead of code messing.
