Hi, This is actually a pretty common issue when moving from PHP 7.4 to 8.x and from what you described, your data is perfectly fine, it’s just compatibility breaking things on the admin side. For us, this is quite straightforward. We will go through the code properly, fix all PHP 8.4 compatibility issues together, and stabilize the admin panel so things stop breaking randomly. Working via AnyDesk/TeamViewer is totally fine. Just a couple of questions: 1. Are PHP errors/warnings enabled on the new server? 2. Is your script fully original or has it been customized? We can jump in, fix it cleanly, and get everything running smoothly on 8.4. What I can guarantee: - Commitment - Frequent communication - Honest approach at all steps Please check reviews, not one of them is less than 5 star (not even 4.9): https://www.freelancer.com/u/WhizPool Thanks, Zeeshan Whizpool

Hi there, I’ve read your project carefully and I’m confident I can migrate your Food Delivery script from PHP 7.4 to PHP 8.4 smoothly, while preserving data integrity and restoring full admin navigation functionality. I’ve worked on PHP 7.x to 8.x upgrades, MySQL/MariaDB migrations, and debugging complex admin UIs where missing menu items or broken JS can cripple workflow. My approach is to validate PHP compatibility, stepwise server configuration, and a controlled DB migration on a staging path, ensuring all admin links, buttons, and payment options load as expected. I’ll work through the exact issues you described, JS events, dynamic menus, and icon rendering, and align them with PHP 8.4's error handling and deprecated features. I’ll share an initial plan and timeline, and after we review a few technical details, I’ll confirm the final cost and delivery schedule. 1) Do you have a preferred window for the migration window and any downtime constraints during the PHP 7.4 to 8.4 switch? 2) Are there any custom PHP modules or third-party plugins in the Food Delivery script I should account for during compatibility checks? 3) Do you have a staging environment on the new server to validate admin UI functionality before going live? Asad - I understand the hidden frictions: you want a reliable, human-led fix rather than iterative AI interactions. I’ll coordinate securely via AnyDesk/TeamViewer, keep changes minimal and reversible, and deliver a tested migration with clear handoff

Hi, I completely understand your frustration — this kind of issue can quickly turn into a loop of fixes breaking other things, especially when moving from PHP 7.4 to 8.4. You’ve already done the hard part by migrating the data correctly. The problems you’re seeing (menus not expanding, buttons not working) are very typical of PHP version conflicts and small JS breakages. This isn’t something that needs endless trial and error — it just needs a careful, experienced pass to fix it properly. I’ll go through it step by step and stabilize everything. We can do it safely via AnyDesk/TeamViewer. I can start immediately. Best,

A Warm Hello! I’ve handled multiple legacy PHP upgrades, and your situation is a classic PHP 7.4 → PHP 8.x migration issue where deprecated functions, array access changes, and outdated libraries break menus, icons, and AJAX-based navigation. What you’re facing isn’t random—it's the script hitting hidden compatibility errors one by one. Here’s how I can help: Review the project structure and identify PHP 8.4–incompatible code (array syntax, deprecated functions, missing type checks, old jQuery plugins, etc.). Fix the admin-side navigation, payment submenu, and any failing AJAX endpoints. Ensure all icons, buttons, pages, and modules load consistently. Fully test the system on your new server to ensure stability before handover. Work entirely through AnyDesk/TeamViewer, respecting the sensitive customer data. I’ve upgraded several PHPJabbers scripts before, so I’m familiar with their structure and older MVC patterns. Most projects like yours take a few hours to fully stabilize. Let’s set up a quick call to discuss things better. Let’s discuss it more in chat. Best Regards, Jemin Sagar

With over 12 years in the field, I have migrated numerous projects successfully, ensuring data integrity and compatibility. Having provided end-to-end software solutions across web, mobile, and backend systems, including APIs, I understand the importance of maintaining functionality during migrations. I recognize your concerns about using AI assistance and the potential time wastage that it entails. My human approach prioritizes clear communication, fast responses, and on-time delivery while keeping you updated throughout the process. I also understand that we are working with sensitive information and am comfortable working via remote access applications such as AnyDesk or TeamViewer to ensure your data's security.

@waqaswebmaster

Hi There This sounds less like a database problem and more like a PHP 7.4 to 8.4 compatibility issue inside the script’s admin panel, where older code, menu logic, or deprecated functions are breaking one fix after another. I can debug it directly on your machine through AnyDesk or TeamViewer, trace the exact incompatibilities, and stabilize the full admin flow without risking your customer data. My focus would be to make the PHPJabbers script fully usable on the new server, not just patch one broken button at a time. Do you already have the new server and migrated script running so I can start by checking the exact errors live? best regards Waqas A.

@anirudhat

I've handled numerous PHP 7.4 to 8.4 migrations and know exactly the cascade of issues you're experiencing—deprecated functions, changed type handling, and updated MySQL/MariaDB driver behaviors that break one thing when you fix another. My approach is systematic: I'll audit the entire PHPJabbers Food Delivery codebase using static analysis tools to identify *all* incompatibilities at once, rather than fixing them one by one like an AI chatbot does, which is exactly why you kept hitting new errors. I'll address deprecated `mysql_*` calls, nullable parameter changes, and the navigation/payment rendering issues in a single coordinated pass. I can start immediately and have deep experience with PHP migration projects and MySQL database compatibility.

@vincentgrerry

Hello.. I can help you fix and migrate your PHPJabbers script from PHP 7.4 to PHP 8.4. I have 17+ years of experience in PHP and have handled many migration and compatibility fixes (7.x → 8.x), including issues with deprecated functions, UI breakage, and backend logic errors. From your description, the issues (menu not working, buttons/icons failing) are likely caused by JavaScript/PHP incompatibility or deprecated code, and I can systematically fix them without breaking other parts. What I will do: - Identify and fix PHP 8.4 compatibility issues - Debug broken navigation, buttons, and UI behavior - Ensure all features work as before (admin + frontend) - Test thoroughly to avoid new issues after fixes I’m comfortable working via AnyDesk/TeamViewer, so your database stays secure on your side. And here is the completed project related upgrade PHP version : - https://www.freelancer.com/projects/php/PHP-Upgrade-Retaining-Existing-Features/reviews - https://www.freelancer.com/projects/php/Convert-mysql-database-query-mysqli/reviews - https://www.freelancer.com/projects/html/Convert-SamPHPweb-SAM-Broadcaster-script/reviews I’m ready to start immediately.

Hi, I’m Parthkumar Virani, a full stack developer with 5+ years of experience, and I’ve handled multiple PHP version upgrades (7.x → 8.x) including fixing compatibility issues in existing scripts. What you’re facing is very common—PHP 8 introduces stricter rules, deprecated functions, and changes that often break menus, JS behavior, or backend logic. The issue is not just the database—it’s mainly code compatibility. Here’s how I’ll handle it: Identify PHP 7.4 deprecated functions and update them for PHP 8.4 Fix backend errors affecting admin panel functionality Debug JS/menu issues (like non-working navigation & buttons) Ensure all modules (payments, settings, etc.) load correctly Test everything step-by-step to avoid “fix one, break another” issues I completely understand your concern about data privacy. I’m comfortable working via AnyDesk/TeamViewer on your system without needing direct DB access. What you’ll get: Fully working system on PHP 8.4 Stable admin panel with all menus and features working Clean fixes without breaking existing functionality Timeline: Initial debugging: few hours Full fix: 1–2 days (depending on issues) I’ve done similar upgrades where small hidden issues kept appearing—so I focus on fixing the root cause, not just patching errors. I can start immediately and resolve this properly so you don’t have to keep chasing issues. Best regards, Parthkumar Virani
