Reliability, Safety & Cache Improvements
New Features
Added an Update Safety Guard that checks whether optimized CSS loads correctly after plugin updates.
Added automatic Safe Mode activation when generated stylesheets fail to load or styling issues are detected.
Added an admin notice explaining when Safe Mode is triggered and why.
Added automatic re-checking after Safe Mode is disabled to help detect recurring styling issues.
Improved
Improved generated CSS reliability by moving stylesheet storage to
wp-content/uploads/optimazz/
.
Improved compatibility with LiteSpeed, WAF configurations, managed hosting, and external CDN or server-level caching.
Improved update recovery by automatically refreshing the page cache when generated CSS storage changes.
Improved website resilience by allowing Safe Mode to pause higher-risk CSS and JavaScript optimizations without changing saved settings.
Fixed
Fixed unstyled pages caused by generated CSS files being removed or blocked in certain hosting environments.
Fixed stylesheet 404 errors caused by unreliable delivery of files stored under
wp-content/cache/
.
Fixed update-related styling failures by adding automatic detection and recovery safeguards.
