Hello Support Team,
Since updating to version 12.6.9, I have noticed an issue. Every time I load a page, a black-and-white screen appears for about 0.1 seconds before the actual content loads (see attached screenshot).
I suspect this might be related to the WP Super Cache plugin, which is also recommended by you. To troubleshoot, I have taken the following steps:
Deactivated WP Super Cache → The issue persists.
Cleared all cache (WP Super Cache & Cloudflare) → No improvement.
Reactivated WP Super Cache and cleared cache again → The problem remains.
This issue did not exist before the update. Could you please advise on what might be causing this and how to fix it?
Thank you for your support!
Best regards,
Greg
Hello,
After extensive 6h testing, I was able to identify the root cause of the issue: The Critical CSS files in Autoptimize apparently generated faulty rules, which led to conflicts with the cache. After deleting the Critical CSS rules in Autoptimize Plugin, caching started working properly again on all pages.
I wanted to share this with you so that you can potentially help other users with a similar problem more quickly. If there is a way to ensure that Critical CSS rules regenerate automatically or to improve error detection in Autoptimize, that would certainly be beneficial.
If you have any questions or need further details, please feel free to reach out.
Thank you for your support!
Best regards,
Greg
