Yes I saw it. Sorry I cannot work on it right now but will update you once I do.
Thank you

Thanks for your answer.

I have w3 total cache. On the setting page, the following are disabled :
– Page cache
– Minify
– Database cache
– Object cache
– CDN
– Reverse proxy
–

Only Browser cache is selected.

I also have the plugin Autoptimize which offer the option, from the top toolbar, to “delete cache”. But I am not sure what it does.

Lastly, I am unsure how to clear cache using that plugin. I always do it with the tool bar at the top Performance>Purge all cache. I think it’s related to the plugin. I have cleared caches using this method many times but it doesn’t change a thing : the unwanted pop up still appears.
