Unusable/Very inconvenient use for my sites.
I’ve tested many caching plugins and every single one pissed me off. One plugin had to many options to configure, another plugin broke my site, another more needed to buy premium version and pay… I just wanted simple cache, and that’s all. So I installed “Simple Cache” as the name says and it works perfectly! We have only few most important options and zero redundant shit 🙂
I already built many sites with this plugin and I’ve never had any problem. Only when you use WooCommerce remember to put cart page URL to “Exception URL(s)” area so plugin will not cache products in the cart.
Does what it should. No hassle.
After install and activating on a fresh WordPress installation, totally broke my site and made it unreachable, even the admin section:
Error 503 Backend fetch failed
Backend fetch failed
Now I have to uninstall it via FTP to make my site recover.

created by Luis Herranz and the Frontity framework.
Breaking Changes:
* The REST API is not cached anymore by default
New Features:
* Cache REST API setting added in advanced mode.

same headers when a cache hit occurs.

Bug Fixes:
* Don’t flush the cache when the user edits a draft post
