Cloudflare APO plugin crashed WordPress site

Hello,

I tried using the “APO” plugin on a WordPress WooCommerce site but I couldn’t activate it due to a “CSRF” token issue. I tried disabling all other plugins on the site but the “APO” still didn’t work (no luck at all).

When I tried to remove the “APO” plugin, the site crashed (Internal server error). Any thoughts on why this happened?

Is the APO compatible with WooCommerce? I read a lot of reviews stating that it is not working when installing with WooCommernce.

Open Issue:

After digging deeper, I found out that the site crashed because PHP is no longer running.
I noticed that when I deleted the CF plugin, the “Permission” on the folders changed, and PHP could not run anymore. I had to restore the folder permission, restore a backup, and the site worked.
