Hey there Brad!
I’ve just tested this on WP7 and cannot recreate this issue, could I ask you to follow the debugging steps given below? These should help identify what’s going on here.
Post the status code + (domain redacted) URL plus the answers from the steps below, and I’ll be able to tell you exactly what’s going on.

Capture the failing request
- Open the page with the Load More button / infinite scroll.
- Right‑click → Inspect → Network tab, and tick Preserve log.
- Trigger Load More (click it, or scroll) until the error appears in the Console.
- In the Network tab, find the request shown in red or with a status like 404 / 403 / 429 / 500. Click it and tell us:
- the Status code, and
- the Request URL (you can redact your domain).
Open that URL directly
- Paste that same Request URL into a new browser tab.
- Does it show posts, a “Nothing found” / 404 page, a redirect, or an error? Let us know.
Describe the setup
- Is the Query Loop set to “Inherit query from template”, or a custom query?
- Is it on your front page, blog page, an archive, or a normal page/template?
- Your Settings → Permalinks setting (Plain vs. pretty permalinks).
If the status was 403 / 429 / 406 / 503
- Temporarily pause any caching/CDN (e.g. Cloudflare) and security/firewall plugins (e.g. Wordfence) and check whether the error clears — those can block or rate‑limit the background
request.
