I’m facing a site-wide 404 error on my WordPress installation. I’ve already tried resetting the permalinks, but every page—homepage included—still throws the error. Because the site runs on both a custom theme and several bespoke plugins, I need a careful, code-safe solution. Here’s what I’d like you to handle: – Diagnose and eliminate the 404 issue (checking .htaccess, database rewrites, plugin or theme conflicts—whatever is required). – Bring WordPress core up to the latest stable release and confirm the update doesn’t break the custom theme or plugins. – Test the full site after the fix so every URL loads normally and all custom functionality works as before. – Provide a brief change log and any recommendations for future maintenance. I’ll supply full cPanel and WordPress admin access along with a recent backup. Once the pages load without errors and WordPress is fully updated and stable, the job is complete.

A 404 on the homepage itself rules out plain permalink rot — that usually points to a siteurl/home mismatch in wp_options, an .htaccess that isn't being read (AllowOverride off or wrong ownership), or a bespoke plugin hijacking rewrite rules or template_redirect. I'll work from a fresh snapshot of files and DB, then diagnose in order: check wp_options and the front-page setting via WP-CLI, regenerate .htaccess, dump rewrite rules, and bisect with a conflict test that toggles plugins from the command line so the live site is never left broken. Core gets updated on a staging copy first, custom theme and plugins deprecation-checked against the new version, then pushed once every URL and custom feature passes. Free to start now.

Hello, Drawing from my extensive skills and experience, I believe I am the right person to fix your WordPress 404 issue. As both a seasoned developer and entrepreneur, I understand how crucial it is to keep things running smoothly for a business. The fact that you have a custom theme and bespoke plugins only elevates the importance of your project, and this is where my expertise in WordPress, PHP, Laravel and rest of the similar associated skills come in. With over a decade of WordPress related experience, I have repeatedly proven my ability to troubleshoot such complex issues with precision. I will methodically examine all potential sources for the 404s, from .htaccess file to your database rewrites. Not stopping there, I also plan on updating your WordPress core to the latest stable release - without breaking anything (quite literally), as part of the job. Once the site pages no longer throw errors and you are satisfied with the working condition of your theme and plugins after the update, I won't mark the job as complete until testing is thorough across all aspects. Finally, you can expect from me a change log along with long-term recommendations for future maintenance. Let's work together and get those pages functioning flawlessly again! Thanks!

Hi, Your site-wide 404 issue usually means WordPress is losing the rewrite path, not just a permalink setting. Since you have a custom theme and bespoke plugins, I’ll approach this carefully: inspect .htaccess, database rewrite rules, plugin/theme conflicts, then update WordPress core and verify nothing on the front end or custom functionality regressed. I’ve handled similar WordPress recovery and upgrade cases with cPanel, backup-safe troubleshooting, and code-aware testing. I’ll keep the fix clean, confirm every URL resolves properly, and share a short change log plus maintenance recommendations once the site is stable. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. Could you also let me know whether the 404 started after a plugin/theme change or server update, and if there’s any custom rewrite logic in your setup? Best regards, Asad Could you also let me know whether the 404 started after a plugin/theme change or server update, and if there’s any custom rewrite logic in your setup?

I’ll trace the site-wide 404 from the server and WordPress layers, starting with cPanel error logs, .htaccess rules, permalink/rewrite handling, site/home URLs, and database rewrite settings. I’ll also isolate any conflict from the custom theme or bespoke plugins by testing them safely against the supplied backup before changing production files. After the URLs are restored, I’ll update WordPress core to the latest stable release using a controlled process, verify PHP compatibility, and check that the custom theme, plugins, homepage, internal pages, and key functionality still work correctly. I’ll test representative URLs, navigation, forms, assets, and admin behavior, then provide a concise change log with maintenance recommendations. I can begin as soon as cPanel, WordPress admin, and the recent backup are available. Is the recent backup a full cPanel backup, or only a WordPress/database backup? Muhammad Saad

Hey, A site-wide 404 where even the homepage fails is usually not a simple permalink problem. In a setup with a custom theme and bespoke plugins, I would first look for broken rewrite rules, incorrect WordPress home/site URLs, corrupted permalink data, .htaccess or server configuration issues, or code intercepting requests before WordPress resolves the URL. I have 10 years of WordPress experience and am in the Top 2% of freelancers, so I will focus on finding the root cause rather than applying temporary fixes. I will diagnose the 404 at the WordPress and server level, fix it safely, update WordPress core, and verify that the custom theme and plugins remain fully compatible. I will then test the complete site, including URLs, navigation, forms, and custom functionality. You will also receive a concise change log and recommendations to prevent similar issues in the future. Since you already have a recent backup and full cPanel/Admin access ready, I can start with the diagnostics immediately. Looking forward to hearing from you. Regards, Muhammad Jawad Abdani
