Hi, 

Some graphics on both  pc version and mobile version stop working after trying to Minify CSS by a plugin called "Autoptimize". 

I'm do not really now how to optmize/minimize my CSS, HTML,... to make my site fast. 

Thanks

Hi Maxime, 

I did follow all steps and even installed WP Rocket which is not free but, receiving  the same result when running the GT metrix scan. Please find attached. 

Thank you in advance 

Is this "wp-rocket-settings-for-sonaar" file  the most efficient setting for my website?  I've imported it but still getting  76 on tools.pingdom.  

I'm not able to import  wp-rocket-settings-for-sonaar.json to my WP-Rocket and WP-Rocket sent me the message below:

WP Rocket names its export files in a specific format, and so it expects the import file to be following that same format -- you can see that format here in our code:
https://github.com/wp-media/wp-rocket/blob/4b8b155c0a3c5543f70867a4b26725e1dbd8457e/inc/admin/admin.php#L545

So, unless you still have a copy of the import file that's still using its original name, you'll need to export again to get a new file (and not change its name so that you'll still be able to import it).

Please advise 

Thanks
