Blank data uris ?

you have something else adding (a lazy load plugin?) that is meddling here @eva2000, even when AO isn’t active, cfr. https://wordpress7.centminmod.com/232/wordpress-7-site-updates/?ao_noptimize=1 with this code in the unoptimized HTML source;

<img  class="aligncenter size-full wp-image-238"  src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" data-src="https://wordpress7.centminmod.com/wp-content/uploads/2016/08/blitzio-10kusers-benchmark-00.png"  alt="" width="686" height="1062" data-srcset="https://wordpress7.centminmod.com/wp-content/uploads/2016/08/blitzio-10kusers-benchmark-00.png 686w, https://wordpress7.centminmod.com/wp-content/uploads/2016/08/blitzio-10kusers-benchmark-00-194x300.png 194w, https://wordpress7.centminmod.com/wp-content/uploads/2016/08/blitzio-10kusers-benchmark-00-661x1024.png 661w" data-sizes="(max-width: 686px) 100vw, 686px" />

find what plugin (could be your theme) that is adding the data-uri with the blank image, disable that and all will be as it should .. ??

hope this helps,

strange only thing i have close to that is https://www.ads-software.com/plugins/async-javascript/ but even deactivated it’s still coming up blank

could be another plugin or even your theme, maybe disable (& reenable) all plugins one by one and even briefly switch themes to identify the culprit?

Yeah seems something changed in customizr theme there’s a image lazy load feature in it that worked with autooptimize fine until latest cutomizr theme update ! For now i have that option disabled and autooptimize disabled and images are showing up again.

well, disabling the theme’s image lazy load with AO active should work as well? if AO turns your bg-images in data-uris, there’s no need to lazy load them any more anyhow?

i think there’s a secondary issue in AO turn on data uris, then turn off data uris will still leave data uris in place.

that’s very likely a cache issue @eva2000; make sure your Autoptimize & page caching plugins’ cache are purged.
