You will get PHP, MySQL, JavaScript, AJAX, and API bug fixes
Project details
Is a PHP feature not working as expected, or is your application showing database, API, AJAX, login, checkout, or server errors?
I will investigate the issue, identify the actual cause, and apply a focused fix without unnecessarily rebuilding your application. I work with custom PHP systems, MySQL databases, JavaScript, jQuery, AJAX, REST APIs, admin panels, payment integrations, and existing business applications.
I can help with:
PHP warnings, exceptions, and fatal errors
MySQL query and database connection problems
Broken login, registration, or session behaviour
AJAX requests returning incorrect or empty responses
Forms that do not submit, validate, or save correctly
Third-party API and webhook errors
Admin dashboard and permission problems
Payment or checkout integration failures
Responsive layout and JavaScript issues
Slow queries and backend performance problems
Before making changes, I review the related code and reproduce the issue where possible. You will receive the corrected implementation along with a clear explanation of what caused the problem.
Plz contact me before ordering if the issue affects several modules or if the application has undocumented custom code.
