If you upgraded to WordPress 6.4 in November 2023 or your installation automatically updated to this version, and you're experiencing issues with blurred thumbnails and images due to using the old Adaptive Images setting, please note that the problem stems from a breaking change introduced in WordPress 6.4.
To resolve this issue, it's recommended to update Uncode to the latest version, which is Uncode 2.8.7 at the time of writing. You can find the update instructions here:
It's important to note that Adaptive Images, responsible for the problem, is an outdated option for creating responsive image crops on Uncode. This feature has been replaced by the newer and more efficient Dynamic Srcset method since Uncode 2.4.0. We encourage you to seize this opportunity and enable the new Dynamic Srcset system, which not only resolves the problem without requiring a theme update but also enhances the performance and user experience of your site.
For guidance on enabling the Dynamic Srcset system, please refer to the following link:
