wp-admin inaccessible: 6-step diagnostic protocol
This technical tutorial (published July 18, 2026 by WP Admin Lab on DEV) presents a six-step diagnostic protocol to troubleshoot inaccessible WordPress wp-admin pages. It categorizes three symptom families — 403 Forbidden, login redirect loop, and white screen of death — and gives concrete fixes: clear cookies and test in private mode, deactivate plugins via WP-CLI or by renaming the plugins folder, regenerate or repair .htaccess rules, and purge caches (browser, plugin, server, OPcache). The post includes exact commands (e.g., wp plugin deactivate --all, mv wp-content/plugins wp-content/plugins.off) and links to more detailed guides on wpadminlab.com.
Practical troubleshooting guide relevant to WordPress site operators and publishers (CMS operations). Useful for site reliability but not industry-shifting.

Fix ERR_TOO_MANY_REDIRECTS for WordPress behind AWS ALB
This technical troubleshooting guide documents a production fix for ERR_TOO_MANY_REDIRECTS when migrating WordPress from an Nginx SSL-terminating setup to one using an AWS Application Load Balancer (ALB) for SSL. Two root causes are explained and resolved: (1) ALB health checks failed with 301 because WordPress redirected health paths — solved by adding 301 to ALB success codes or pointing health checks to a 200 endpoint; (2) a redirect loop caused by Nginx redirecting HTTP to HTTPS while ALB performed SSL termination — solved by removing Nginx HTTPS redirects, listening only on port 80, setting fastcgi_param HTTPS on, and adding a wp-config.php snippet that sets $_SERVER['HTTPS']='on' when X-Forwarded-Proto is 'https'. Tested on Ubuntu 22.04, Nginx 1.24, WordPress 6.x.
Optimizing WordPress Databases with Essential WP-CLI Commands
This technical guide highlights the utility of WP-CLI commands `wp db check` and `wp db optimize` for maintaining WordPress database health. Over time, WordPress databases accumulate bloat such as spam comments, expired transients, and fragmented tables. The `wp db check` command verifies table health and identifies database corruption, while `wp db optimize` defragments tables and reclaims unused disk space, particularly for older MyISAM or standard InnoDB engines. The guide advises running these commands after bulk deletions, before major updates, or as part of routine maintenance. Additionally, `wp db repair` is recommended as a recovery option for corrupted tables, provided a fresh backup is taken beforehand.
Fix Mixed Content and SSL 'Not Secure' in WordPress
This technical how-to explains why browsers show a "Not Secure" label after moving a WordPress site to HTTPS (mixed content: some page resources still load over HTTP) and gives a step-by-step remediation. Recommended actions: verify a valid SSL certificate and site URLs in Settings → General; use the browser console to identify insecure http:// resources; run a serialized-safe database search-and-replace (or use trusted plugins) to update old HTTP URLs; force HTTPS site-wide (plugin or .htaccess redirect on Apache); and fully clear all caches. The guide warns against raw SQL replacements that break serialized data and recommends taking a backup before any database-wide changes. It also notes common tools and pitfalls and stresses clearing CDN/host/plugin/browser caches to confirm fixes.
