I was trying to add this site to Indieweb ring last night and found that it couldn’t validate the presence of the previous/next links, even though they were clearly in the footer of every page. I cleared the WordPress and Cloudflare caches without success.

Since Indieweb ring runs on Glitch, which is a large public service, I suspected that maybe Cloudflare was blocking their traffic. Sure enough, checking my http access logs I couldn’t find any requests from Glitch, and switching nameservers to my web host resulted in a successful check:

This was happening even with the “Bot Fight” option set to off, “Security Level” set to “Essentially Off” and a disabled “Browser Integrity Check” option.

[side note] I love that my autogenerated site identifier for Indieweb ring is a person worried about taking pictures and writing. Accurate.
