WebP Lighthouse and PageSpeed Insights

In order to serve WebP to WebP enabled browsers and JPEG to other browses, you must configure Apache .htaccess as described in plugin “Help”.

Hi,
Thank you for your reply.
I configured .htaccess as described in Help.
Also I cleared the cache.
I do not know what other setting should I do.

.htaccess itself may not be enough, configured/used Apache modules must be enabled. Maybe you have Nginx server? Maybe you use CDN that is caching first response?

I have used another plugin and was loading webp just fine.
I have Apache and W3 Total Cache, with no CDN.

I can only guess that you don’t have either “mod_mime” or “mod_headers” enabled.

If your WordPress install works with “pretty permalinks”, “mod_rewrite” is enabled

Could you be more explicit on how exactly should I check mod_mime and mod_heders?
Thank you

Depends. If you have cPanel you will find it somewhere there.

Else ask your hosting provider, he would know what is going on. So far, from 1000+ installs, only one user had reported such a problem.

I will contact my hosting provider and let you know.
Thank you for your kind support.

Hi,
The provider confirmed me that both “mod_mime” and “mod_headers” are activated on server.
What should I do next?
Could be a Theme issue?
I really need your plugin.
Thank you

I do not know. Plugin only compress/create images on backend/admin side. Apache (htaccess) should deliver to WebP enabled browsers.

W3 Total Cache maybe keeps caching JPEG image? Can you disable image caching? Or temporary disable caching plugin?

Hi
I disabled W3 Total Cache and now it loads WebP images.
Response Headers ” content-type: image/webp ”
Request Headers “Accept image/webp,*/* ”
Do you think YOAST could work better with your plugin?

Not YOAST of course ??
Any other Caching Plugin that works better with your plugin.
I do not see anywhere a donation link.
Thank you

About caching plugin(s):
You may check if caching plugin has added it’s own rewrite rules before Warp-iMagick rewrite rules (.htaccess file). If so, move Warp-iMagick rewrite rules back on top of .htaccess file.
