Hi,
you must have changed something significant between Pro 6.6.10 and 6.7.0 (and all following releases) regarding backgrounds. It’s also somehow written in the changelog (“Feature: Background layers has breakpoint support”, “Feature: Background image background-attachment controls”)
Sadly right after the update on August 5, 2025 our site was broken: many background images where missing or background colors where showing as white on frontend.
I immediately reverted back to a backup and used the last month to slowly work my way through the troubleshooting on our staging site. Today I can say: The problem is related to Pro 6.7.0 and WP Rocket’s “remove unused css”. When using the feature on your 6.7.X css like
.mqw-9.x-section {
background-color: #173952;
}
are missing and that is causing the sections to appear white on frontend.
I do know that WP Rocket’s not your business and you will recommend to hire your service Boost but WP Rocket did not change anything on their end recently. Everything was (and is when downgrading) working flawlessly for years until your update. For now all my projects are stuck on Pro 6.6.10 and that’s sad. So any other other suggestion than stop using WP Rocket’s “remove unused css” or hiring Boost is welcome! Do you have any idea what could have caused this? Must be a bigger change in the background then just adding some toggles for responsiveness?
I am wondering if somebody else has reported this issue? Thank you
