Igor A
About this gig
If your WordPress website stopped working after a PHP upgrade, shows fatal errors, deprecated warnings, white screen, or plugin crashes I can help.
Many hosting providers automatically update PHP to version 8, and older themes, plugins or custom code become incompatible. This often results in PHP 8 compatibility issues, undefined functions, deprecated function warnings, 500 errors, or WooCommerce checkout problems.
I will professionally diagnose and fix PHP 8 errors in WordPress, including:
- Fix fatal errors and parse errors
- Remove deprecated warnings
- Debug theme compatibility issues
- Identify and replace incompatible plugins
- Rewrite problematic PHP code if necessary
- Restore WooCommerce functionality
- Fix website broken after hosting PHP update
If required, I can safely upgrade PHP to version 8 or higher and ensure your site runs smoothly and securely.
Every job includes proper debugging, compatibility testing and careful implementation.
Lets make your WordPress fully compatible with PHP 8 and stable again.

FAQ

Do I need to upgrade to PHP 8 ?
Most modern plugins and WooCommerce require PHP 8 for performance and security. Staying on older versions can cause security risks and compatibility problems.
Will you make a backup before making changes?
Yes. I always recommend and create a backup before modifying files, plugins, or upgrading PHP versions.
Can you fix WooCommerce issues after PHP update ?
Yes. I fix checkout errors, cart issues, payment gateway problems, and plugin conflicts caused by PHP 8 compatibility issues.
What if the problem is caused by a plugin or theme ?
I will identify incompatible plugins or theme code. If needed, I can rewrite problematic PHP code or suggest safe alternatives.
Do you fix custom-coded WordPress websites ?
Yes. I can debug and repair custom themes or plugins with PHP 8 compatibility errors.
What access do you need ?
Temporary WordPress admin access and access to your hosting control panel or server are required for proper debugging.
