Upgrade Site to PHP 8.4 (With Avada Theme Purchased Version)

I need the entire code-base of my website brought up to full compatibility with PHP 8.4. The site currently runs user authentication and a blog, and it relies on several custom plugins that will all need individual attention during the upgrade. Because I'm not yet sure which functions or libraries will break, I'm looking for someone who can first audit the project, flag anything deprecated, and then refactor or replace it so the site runs error-free in a PHP 8.4 environment. That includes combing through core files, the theme, and every custom plugin to make sure type declarations, strict comparisons, and any new engine changes are handled correctly. Deliverables • Comprehensive compatibility audit report • Updated source code for core site and all custom plugins • Functional testing proof (authentication flow, blog CRUD) on PHP 8.4 • Clear change-log so I can track what was modified I'll provide full repository access and a staging server running PHP 8.4 for validation. The web is make in wordpress, and use the theme Avada 5.6.2 version, the version is registred , and i need update the theme to Avada 7.16.1.

Being thorough and detailed-oriented, I'll conduct an exhaustive audit of your project, listing every single deprecated element to then refactor or replace them for smooth compatibility with PHP 8.4. Additionally, as proof of concept and transparency matters, providing you a comprehensive compatibility report, along with an updated source code, functional testing proof on PHP 8.4, and a clear change-log will be at the top of my priority list.

It would be a pleasure to bring my VARIED toolbox including jQuery, CSS3 & HTML5 PLUS any programmin Thanks! €30 EUR in 1 day €30 EUR in 2 days €25 EUR in 1 day €30 EUR in 1 day €10 EUR in 7 days Your WordPress upgrade requires more than a PHP version change: Avada 5.6.2, custom plugins, authentication, and blog functionality must all remain stable on PHP 8.4 and the newer Avada 7.16.1. I can audit the repository and staging environment, identify deprecated PHP and WordPress patterns, then refactor the core code, theme customizations, and each custom plugin for compatibility. I will also validate login flows and blog CRUD operations on PHP 8.4 and provide a clear audit report, change-log, and testing evidence. I recommend reviewing Avada-specific overrides and child-theme dependencies before updating, so customizations are preserved rather than overwritten during the theme transition. I will keep the upgrade controlled through staging, incremental changes, and regression testing before production deployment. Regards, Muhammad €25 EUR in 1 day Hello, With over 6 years of experience in PHP development and WordPress customization, I am confident in my ability to upgrade your website to PHP 8.4 while ensuring compatibility with the Avada theme (from version 5.6.2 to 7.16.1). I will conduct a thorough audit of your codebase, identify and address any deprecated functions, and update the source code for core files and custom plugins accordingly. Using best practices and attention to detail, I will provide you with a comprehensive compatibility audit report, updated source code, functional testing proof on PHP 8.4, and a clear change-log for tracking modifications. Rest assured, your website will run error-free on the latest PHP version. Thanks, Shahbaz Khan €19 EUR in 2 days Hi, I've handled similar WordPress/PHP compatibility upgrades where legacy themes and custom plugins require careful refactoring rather than a simple version switch. The main challenge here is ensuring PHP 8.4 compatibility while upgrading Avada 5.6.2 to 7.16.1 without breaking authentication, blog functionality, or custom code. I'll audit the core, theme, and plugins for deprecated/incompatible code, create a safe upgrade path, refactor affected functions, and validate everything on your PHP 8.4 staging server. I'll test authentication and blog CRUD, resolve errors, and provide the audit report, updated code, and detailed change-log. Best Regards, Muhammad Saad K €10 EUR in 4 days €8 EUR in 1 day €70 EUR in 1 day Hi, I can audit and upgrade the WordPress installation for PHP 8.4 while carefully migrating Avada from 5.6.2 to 7.16.1 and preserving existing content and functionality. I'll work in staging with a verified backup and rollback point. The audit will cover WordPress, Avada/Fusion-to-Avada Builder changes, child-theme overrides, custom plugins, hooks, shortcodes, templates, dependencies, deprecated PHP behaviour, dynamic properties, type errors, database queries, and runtime warnings. WordPress core will be updated through supported releases rather than manually modified. Custom code will be refactored with focused, version-controlled changes. Testing will cover login, password recovery, roles, sessions, blog CRUD, media, responsive layouts, forms, menus, widgets, and Avada templates under PHP 8.4. You'll receive the compatibility report, updated code, test evidence, and a detailed change log. Three technical questions: 1. Which WordPress, PHP, database, and plugin versions are currently running? 2. Does the site use a child theme or direct modifications inside Avada? 3. How many custom plugins exist, and are any encrypted or dependent on abandoned libraries? Best regards, Houssame €250 EUR in 7 days €16 EUR in 5 days Hello To ensure your website runs smoothly on PHP 8.4, I will conduct a thorough compatibility audit of your entire code base, focusing on the core files, the Avada theme, and all custom plugins. I'll identify deprecated functions and refactor the code as needed to guarantee error-free performance. Deliverables will include a comprehensive audit report, updated source code, testing proof, and a clear change-log. https://www.freelancer.com/u/KhawajaaAli Before I lock in the approach, could you share any specific custom plugins you're particularly concerned about during the upgrade? Best regards, Khawaja Ali €15 EUR in 1 day €8 EUR in 3 days €19 EUR in 3 days Yes – I can upgrade your entire WordPress code‑base to full PHP 8.4 compatibility, including updating Avada from 5.6.2 to 7.16.1. I'll audit core files, theme, and all custom plugins for deprecated functions/type declarations/strict comparisons, refactor/replace as needed, and deliver a comprehensive audit report, updated source code, functional testing proof (authentication, blog CRUD) on PHP 8.4, and a clear change‑log. I'll work on your staging server with full repository access. Available now – ready to start. €19 EUR in 3 days Hi, The real challenge here isn't just updating PHP—it's that your custom plugins were likely written before strict typing and deprecation warnings existed, so they'll surface hidden issues once you move to 8.4. Add the Avada theme jump from 5.6.2 to 7.16.1, and you need a systematic approach to avoid breaking authentication or the blog during the transition. I'd start with a detailed audit on your staging server, running PHP 8.4 with all error reporting enabled to catch deprecated functions, type mismatches, and incompatible library calls across your core files, plugins, and theme. Once I have a clear picture of what breaks, I'll refactor the code in order of risk—authentication first since that's critical to your users, then blog functionality, then remaining plugins. Each change gets tested individually before moving forward. The key decision is doing this in stages rather than all at once. I'll keep the changelog detailed so you can see exactly what changed and why, and I'll validate the entire flow on staging before anything touches production. That way you have a clear rollback path if needed, and you'll understand what was modified for future maintenance. The payoff is that your site runs on current PHP with proper type safety, your custom code becomes easier for any developer to maintain going forward, and you're not sitting on deprecated code that will cause problems again in two years. I can start with the audit right away. Thanks, Felix. €20 EUR in 1 day Hi there ! This is Persia Michael who are expert in PHP 8.4 Migration • WordPress Audit • Custom Plugin Refactoring I understand you need your WordPress site fully compatible with PHP 8.4, including core files, theme, and custom plugins. The main challenge is identifying and fixing deprecated functions, type declaration issues, and strict comparison errors. You also need the Avada theme updated from version 5.6.2 to 7.16.1. My approach begins with a complete audit of the codebase on your staging server. I will run the site with error reporting enabled, scan for deprecated functions, and test the authentication flow and blog CRUD operations. For each custom plugin, I will refactor any incompatible code, ensuring proper type declarations and strict comparisons. I will update Avada to 7.16.1 and verify that all customizations remain intact. After fixes, I will test everything thoroughly on PHP 8.4 and provide a detailed change-log with every modification documented. I have a couple of important questions about this project. Q1 - Can you confirm if all custom plugins are currently maintained or if any are no longer supported? Q2 - Do you have a child theme in use, or were modifications made directly to Avada files? I look forward to chatting with you along with the answer to the questions above. €25 EUR in 2 days Hey , I just went through the project description, and I see you are looking for someone experienced in Software Testing, WordPress, Website Optimization, PHP, Web Application Audit, Web Development, HTML and MySQL.
