Capability sweep (recipe r20): recipe r22 without the login lockout
站主看到什麼
The problem types in the item list were introduced at the same time into a copy of an online store test site. After that, the homepage returned HTTP 200, the login page returned HTTP 500, and the WordPress dashboard would not load.
出處：能力掃描（把「修得了什麼」頁上的一項或多項故障植進同一個測試站），沒有單一論壇帖。
測試環境與弄壞後看到什麼
測試站：WordPress 7.1、PHP 8.3。下表是照配方弄壞之後，首頁與登入頁回的 HTTP 狀態。
| 主機環境 | 首頁 | 登入頁 | 備註 |
|---|---|---|---|
| Apache + PHP-FPM | 200 | 500 | |
| Apache + php-cgi (mod_cgid) | 200 | 500 | |
| Apache + mod_php | 200 | 500 | |
| nginx + PHP-FPM | 200 | 500 |

缺口與修在哪一版
結局不是修好的跑次，都在這裡：改了什麼、修在哪一版、重跑的日期與結局。
| 發現日 | 主機環境 | 連線模式 | 改了什麼 | 修在哪一版 | 重跑 |
|---|---|---|---|---|---|
| 2026-11-08 | nginx + PHP-FPM | FTP | Write-back over encrypted FTP stopped partway on this server because of how our FTP client set up encrypted connections, so the case ended as not recovered. The FTP client was changed. | 2.1.443 | — |

補充
Recipe r20 is recipe r22 without the login lockout. Only problem types listed on the What we fix page are shown. One of them, a database table collation mismatch, could not be created on the database servers used here, so it was not introduced and is not listed. The fix for the gap below was re-tested with recipe r22, which contains every fault in this recipe; see the r22 record. WP admin mode was not run in this series.
