I edited the .htaccess rule with cache-control instead of expires while disabling and re-enabling WP Super Cache and that did the trick!

Thanks again for the valuable plugin and prompt feedback! ??

Sorry for late reply.

I disabled “static delivery” and while it fixes the CSS expiry, Pagespeed Insights is now reporting four PHP files expiry in 10 minutes.

Also I updated WordPress to 4.9 in the latest test.

That will be great if you can fix it (although I’ve been repurposing your Retina feature for different purpose haha :D)

I’ll wait for the next update instead over here. Glad you found a way to fix it!

Guess what it works haha. I verify it by temporary commenting out the $content_width and enable Large@2x only.

I regenerate the thumbnails since I removed all the excess unused thumbnails and since the new Large@2x (which I set it at 800px which is double of the Large 400px value), it replaces the 200px min width srcset to use the 800px instead of the 400px thumbnail.

Sadly I still need to enable $content_width for some of the plugins on my site.

Yes I set mine using the $content_width variable in functions.php and also through the CSS.

Although my theme is based on Touchfolio which I tweak a lot to keep it lean as the default settings proves to be really heavy for mobile connection slower than 3G.

Hi Stefan, WordPress did generate the thumbnails for the new image sizes that I added through the functions.php.

I’ll check it out later after my sleep. Also I noticed your documentation over at GitHub is more thorough than the one over here! Guess you want to update the screenshot section too to better reflect the plugins settings.

Well I try adding in the custom @2x add_image_size but for unknown reasons, it doesn’t add or inject the retina image?

I know the plugin settings did pickup the new @2x size that I added in the functions.php but I got no idea to verify if WordPress actually regenerate thumbnails for the @2x sizes.

Your documentation did show an example of regular and regular_retina pic inline in the HTML example but mine only show the regular image that is set by the Media settings and not the @2x sizes.

So after careful inspection in the HTML code that enabling Retina means serving images one size larger than the size specified at the Media settings, I decided to use it to my advantage by configuring the Large and Medium sizes for Mobile devices.

My current content width is 730px so for specific images that I need to be Retina quality, I just save at 1460px width and insert the full size image into my post. It will look super big in the post editor but my CSS is configure to scale images to fit the content width proportionately. So instant Retina display on the iPad with Retina display.

Hope you don’t mind the long reply as I hope others can learn my newfound trick with your plugin. ??
