Title: Blank data uris ? Last modified: February 25, 2017 --- # Blank data uris ? * Resolved [George Liu](https://wordpress.org/support/users/eva2000/) * (@eva2000) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/) * Hi I am having a weird problem that just started today. My data uris generated by Autooptimize are all turning up blank for the thumbnails ? * Example is image thumbnails at [http://wordpress7.centminmod.com/232/wordpress-7-site-updates/](http://wordpress7.centminmod.com/232/wordpress-7-site-updates/). Turning data uris generation on or off and clearing all caches don’t have any effect. Accessing data uris directly in Opera 43 and Chrome 56 on Windows 10 result in same blank images.

[http://wordpress7.centminmod.com/232/wordpress-7-site-updates/?ao_noptimize=1](http://wordpress7.centminmod.com/232/wordpress-7-site-updates/?ao_noptimize=1) with this code in the unoptimized HTML source; * ``` ``` * 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, frank * Thread Starter [George Liu](https://wordpress.org/support/users/eva2000/) * (@eva2000) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/#post-8847756) * strange only thing i have close to that is [https://wordpress.org/plugins/async-javascript/](https://wordpress.org/plugins/async-javascript/) but even deactivated it’s still coming up blank * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/#post-8848054) * 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? * Thread Starter [George Liu](https://wordpress.org/support/users/eva2000/) * (@eva2000) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/#post-8851506) * 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. * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/#post-8851750) * 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? * Thread Starter [George Liu](https://wordpress.org/support/users/eva2000/) * (@eva2000) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/#post-8851846) * 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. * Plugin Author [Frank Goossens](https://wordpress.org/support/users/futtta/) * (@futtta) * [9 years, 2 months ago](https://wordpress.org/support/topic/blank-data-uris/#post-8852431) * that’s very likely a cache issue [@eva2000](https://wordpress.org/support/users/eva2000/); make sure your Autoptimize & page caching plugins’ cache are purged.
