Well, after messing around with it, it seems to be working.
I had the plugin turned off for the past few days, so I turned it back on again, cleared the cache, and checked.
I was using Firefox, and the image wasn’t showing.
So I checked other browsers (Chrome, Safari, Vivaldi, IE) and found that it was displaying correctly.
I also tried it on my iPhone, and it displayed correctly there.
I then checked the Adaptive Images folder in /public_html/wp-content/cache/adaptive-images and found that the cached images were there by name for the iphone resolution (460), but in the laptop’s folder (1400), there was an image called something like content-filler.png.
I quit Firefox, then restarted it and checked again. Now the image shows in that location by its proper name.
The site only has two images at this point, so there’s not a lot to check.
There are two watched directories under the plugins settings:
wp-content/uploads
wp-content/themes
The cache directory is:
cache/adaptive-images
Here are the diagnostics you requested. I’ve changed the domain name and account name:
✔ PHP GD library is installed.
✔ Image cache directory has been created.
/home/account/public_html/wp-content/cache/adaptive-images => drwxr-xr-x
✔ Installation .htaccess file is setup OK.
/home/account/public_html/.htaccess => -rw-r–r–
