...an absolute minimum. You can use my AI agent or yours if needed. Key points • No email accounts are tied to this site, so mail transfer is not part of the scope. • Once the site is on the VPS it must load securely over HTTPS, process orders, and preserve every permalink, product, image and plugin setting exactly as they stand today. • I expect the usual LAMP/LEMP components (PHP, MySQL, Apache or Nginx plus SSL) to be tuned for speed and stability; feel free to suggest the stack you’re most comfortable with.

...Java/JSP security-minded developer to help me replace a single hyperlink on the Northern Railways site (page: ,4,385). The current link points to and must be updated to At the moment I have no server access, so the first step is a brief audit of the page structure, its deployment flow (likely Apache Tomcat on a Linux host), and the exact permissions or credentials required to make the change safely. I will supply our internal security documentation; all work must respect those protocols. Once you outline the legitimate method and confirm the level of admin or code-repository access I must secure, I’ll arrange that access. Afterward, you will implement the link swap and verify it in production

Website: Php 8.1.32 Joomla! 4.4.14 Stable [ Pamoja ] 30-September-2025 16:00 GMT Apache/2.4.37 (Rocky Linux) OpenSSL/1.1.1k Mysql 8.0.41 Our Joomla-based online store—which uses a custom mobile phone case configurator to process orders—has just been flagged as infected with malware. Scans indicate infections within the core Joomla files, while the configurator code remains intact as it operates independently of Joomla. Unfortunately, I do not have a recent backup to restore the site from, so it must be cleaned in place and then fully secured. Here is what I need: • A comprehensive, documented scan of the filesystem and database to isolate and remove any malicious files, scripts, or backdoors. • Restoration of all legitimate core Joomla files, followed by ve...

Feel free to pick the web server stack you think best (Apache, Nginx, or something leaner)—I have no strict preference as long as the final container serves the app reliably. Deliverables will be: 1. Dockerfile committed back to the repo. 2. Any accompanying . 3. Running container on the EC2 instance, verified by visiting the URL. 4.

...site occasionally drags or times out. I need a developer who can dig into both sides of the problem: • Restore full, stable access to wp-admin (login page, dashboard, post editor, media uploads, everything). • Investigate what is pushing the server load so high and outline concrete steps to bring it back to normal—whether that’s cleaning up runaway queries, optimising PHP-FPM, tweaking Nginx/Apache configs, or pinpointing a heavy plugin. You will have cPanel/SSH, phpMyAdmin, and WordPress admin (once fixed) to work with. Please document the root causes you find and the changes you apply, then suggest any longer-term improvements—caching layer, object cache, CDN, or better hosting tiers—if they’ll keep the site healthy.

Our Zen Cart 1.5.7c e-commerce site (PHP 8.2, Apache/Plesk, MariaDB) is returning an HTTP 500 error on the home page and category pages. We need an experienced Linux/Apache/PHP-FPM engineer to find and fix the root cause. This is a server infrastructure diagnosis job, not a typical "fix my Zen Cart" job. We've already done extensive testing and ruled out the application code as the cause. We need someone comfortable tracing requests at the web-server/PHP-FPM layer, not someone who will start by reinstalling Zen Cart or clearing caches. WHAT WE'VE ALREADY DONE (please read before bidding): Fixed a MySQL connection-limit issue that was causing a separate, unrelated batch of errors (confirmed resolved). Enabled Zen Cart's file-based error logging, whic...

...endpoint is stable, it needs to be consumed by either the Angular or React interface with a responsive, polished user experience. The codebase lives in Git; each feature is tracked in small Jira tickets so the scope stays tight. After completing a ticket, simply open a pull request, add Swagger or Postman collections for quick testing, and walk me through the changes on a short call. GraphQL, Kafka, and AWS sit on the roadmap for later phases, so prior exposure to those tools will definitely help when we begin integrating messaging and cloud deployment. Deliverables per ticket • Spring Boot REST endpoint(s) fully functional and tested • Updated Angular or React components hooked to those endpoints • Swagger / Postman documentation for the new API surface &b...

Documentation is delivered in a simple markdown or text file. If you’ve battled mixed-type bot storms on Apache before and can work over SSH with minimal dow...

I need a lightweight dashboard added to the dental-clinic site you built earlier. The goal is straightforward: let the staff pull up patient feedback and appointment history, filter the results by date range, and immediately export what they see to a CSV file. The front end must be written in Apache Flex (same version you used on the main site) and plugged into the existing MySQL database. I’ll give you the current schema and connection credentials; no changes there, just read-only queries. Please push all code to the clinic’s private Git repo, mirroring the branch structure we already use. Turnaround is tight—one working day—and the clinic has capped this task at $50, so I’m keeping the scope laser-focused: • Flex module (or SWF) that drops nea...

No themes or plugins were updated and no code edits were made right before this happened, so I’m expecting you to dive straight into log files, plugin conflicts, database integrity, and PHP version compatibility to uncover what went wrong.
