FAQ
What information do you need from me to start fixing the bugs?
Please provide a clear description of the problem, screenshots or a short screen recording of the bug, and a link to your website. If the fix requires changes under the hood, I might also need temporary login access to your website's admin panel (WordPress) or hosting/FTP.
Can you fix bugs on platforms other than WordPress?
Yes! While WordPress is very common, I can fix frontend, styling, and responsiveness layout bugs on any website that uses standard HTML5, CSS3, and JavaScript, regardless of the platform.
What happens if the bug cannot be fixed or comes back?
Your satisfaction is my priority, which is why I offer unlimited revisions. If a bug reappears due to my code, I will fix it for free. In the extremely rare case that a bug is completely unfixable due to server-side or third-party limitations, we can cancel the order and you will get a full refund.
