Unable to activate Browser Caching

Hi guys,

I had the browser caching unable, we did some test and we deactivated it. Now every time when we activate the browser caching on our site we get an error.

Browser Caching is not working properly:
- Your server may not have the "expires" module enabled (mod_expires for Apache, ngx_http_headers_module for NGINX)
- Another plugin may be interfering with the configuration
If re-checking and restarting does not resolve, please check with your host or open a support ticket with us.

We see the .htaccess beeing edited, but for the 4 type of file it still say disable.

I try deactivated all plugin and activated the browser caching again, same issue. mod_expires is on our server as it was working before...

Could you please help us ?
