Hi, I have this problem for a few months already and have no idea how to fix this.
When Cloudflare is enabled, my website meditatieinstituut dot nl (I cannot add link) gives a 403 status response (you cannot see this when visiting the website, but you check it for example with httpstatus dot io).
At this moment I have turned Cloudflare off, since Cloudflare is suggesting it have to be on the side of my host. But when Cloudflare it paused, it gives a 200 status response.
I don’t understand why Cloudflare turns this into a 403 response when enabled.
In a previous topic I started (and is closed now), @ [neiljay] told me that the admin-ajax.php file is causing the 403 response.
But I cannot replicate this error. Maybe I don’t now how to, so if anyone can please tell me how to check this? I tried with the inspecter tool, but maybe I’m using this wrong…
I hope someone can help me with this problem that’s there for too long now 
Thanks!
