FAQ
What information do I need to provide before you start fixing the bug?
Please provide a brief description of the issue, screenshots or recordings of the error, and access to your source code (repository link or zip file). If the issue involves a specific user action, let me know the steps to reproduce it.
Can you fix bugs on a live production website?
To ensure safety, it is always best to work on a staging or development version of your website. Once the bug is completely resolved and tested locally, the clean code can be safely deployed to your live website.
What happens if the bug requires more work than the package price?
If the technical issue turns out to be a massive architecture problem rather than a standard bug, I will clearly explain the root cause to you first and provide a transparent, custom offer tailored to the actual scope of work required.
