What is the name of the domain?
What is the error number?
No specific error number displayed, but performance tools (PageSpeed Insights, GTmetrix) report extremely high TTFB values when APO is enabled.
What is the error message?
No browser error message — however, TTFB consistently exceeds 1.5 seconds, and mobile PageSpeed score drops from ~90 to below 50 after enabling APO.
What is the issue you’re encountering
I recently activated Automatic Platform Optimization (APO) for my WordPress site at 2048cupcake.online, hoping for performance boosts. Instead, the opposite happened: Mobile PageSpeed scores tanked (from ~90 to below 50) Desktop scores dropped from ~97 to ~78 TTFB shot up to 1500ms+ Only dynamic pages are affected — static pages are less impacted
What steps have you taken to resolve the issue?
Here’s what I’ve done so far:
- Cleared Cloudflare cache and my WordPress cache (LiteSpeed Cache)
- Disabled APO — performance immediately returned to normal
- Tested in Incognito and across multiple networks/devices
- Verified issue using tools like PageSpeed Insights, GTmetrix, WebPageTest
- Enabled/disabled Rocket Loader — no improvement
- Confirmed edge cache status — many requests show cf-cache-status: MISS
What are the steps to reproduce the issue?
Visit 2048cupcake.online with APO disabled → PageSpeed scores are great
Enable APO via Cloudflare dashboard → Wait for cache to rebuild
Retest on PageSpeed or GTmetrix → TTFB increases dramatically, especially on mobile
Observe PageSpeed suggestions — all point to server response time being too slow
