At least I think that is the cause, because I found it mentioned here few times, without a solution.
Being on full or full strict mode does this. I realised that in wp-admin in general, it is origin server’s ssl, but on “/wp-admin/post-new.php” browser uses CF’s SSL, this is probably the problem. Any solution?
Also if I try flexible or off, site gets into loop because CF is forcing http but site is https.
This quite surprised me because I applied CF on few sites already without issues.
Hi @marek.jakubcik1,
If your DNS records are proxied, Cloudflare’s Universal SSL certificates are used for all traffic that is going through the proxy. Have you tried purging your cache?
Are you using APO? If so, could you try disabling plugins on your origin to check if there is any compatibility issue that is affecting your site?
It did start to work in the meantime, I don’t know what exactly fixed that, I tried many random things, which at first didn’t seem to work. It is on free CF only btw.
