I noticed you added a code, but where is it suppose to be placed. Also, Cloudflare had your side messed up one day. I had to take it off for the same reason. I did all the fix it stuff, but it still gave me the same results….just an FYI
I’ve added support for infinite scroll in the next version, there were a large number of changes that had to be made for it to work. The code I posted on my site here was only a small part of the code changes.
As far as cloudflare, I know of countless sites using this and Techozoic and working just fine. Some of your plugins are probably causing problems with caching.
