wp-content/cache/all//index.html

In most cases this is resolved by clearing the cache of fastest cache, or clearing, deactivating, and activating again.

Possibly you need to re-save the permalinks.

Let me know if this helps!

Hi Rogier, I discovered that the suggested fix from Fastest Cache is working, but the browser cache isn’t showing the results. Incognito modus learned that this fix is really working. https://www.wpfastestcache.com/tutorial/redirection-to-wp-contentcacheallindex-html-problem/

As discussed with the developer from Fastest Cache, I’ll add this fix with the .htaccess redirect when Fastest Cache is detected.

Excellent work!
