WordPress Performance & Security Fixes
Budget: ₹1,500 – ₹12,500 INR
My self-hosted WordPress site (Nginx, PayU gateway, Jetpack active) has developed a handful of urgent problems that now impact both customers and search visibility. I would like one seasoned WordPress troubleshooter to diagnose the root causes, implement fixes, and leave the installation clean, fast, and secure.
Key problems to resolve
• “414 Request-URI Too Large” appears inside wp-admin whenever I try to access settings or other back-end pages.
• Front-end pages regularly take 5-10 seconds to load, even on a fresh browser session.
• The site drops offline or becomes unresponsive 5-10 times a day for 5-15 minutes; Jetpack emails arrive with reference 207729770/intermittent.
• Google is indexing Japanese product spam—signs of malware or a residual hack.
• PayU payment gateway hangs on the redirect back to my store. The PayU logo keeps blinking and orders remain stuck in “Payment Pending.”
• Main logo flickers multiple times on several pages.
What I expect from you
• Locate and fix the cause of the 414 error (likely Nginx, php-fpm, or a plugin sending oversized queries).
• Optimise performance: database, image, cache settings (Object Cache, page cache, or equivalent) and verify TTFB under 1 s.
• Identify why the server or PHP workers crash and put permanent safeguards in place (logs, limits, WP-CLI health checks).
• Remove all spam/hacked content, patch vulnerabilities, harden WordPress (latest core, theme, plugin updates, file permissions, security plugin of your choice).
• Restore seamless PayU workflow all the way to order-received page; verify status updates inside WooCommerce.
• Eliminate the logo flicker by correcting CSS/JS conflicts or theme glitches.
Acceptance criteria
1. Admin area reachable without 414 errors for 7 consecutive days of testing.
2. GTmetrix or WebPageTest shows fully-loaded time < 3 s on the home page.
3. UptimeRobot (or similar) reports 99.9 % uptime over 7 days.
4. Google Search Console clean of Japanese spam after re-index request.
5. End-to-end test transaction via PayU records as “Completed” in WooCommerce and redirects to the order confirmation page.
6. Logo displays once, without flicker, across template pages.
Access provided: SSH, wp-admin, PayU sandbox, and Jetpack logs.
Please outline your approach, estimated timeframe, and any additional security or monitoring tools you plan to deploy.
