FAQ
Why is CMF (Contact Me First) mandatory for this Gig?
Bug complexity varies widely. A seemingly small error might require hours of work. Contacting me first allows me to assess the actual scope and create a Custom Offer that delivers the best value without risking cancellation.
What information do you need to start the Bug Fix?
I need the exact error message (or a screenshot), temporary access credentials (FTP/SSH/WP Admin, etc., which you can share securely on Fiverr), and the URL where the issue is occurring.
Is the $50 Basic Package enough for any bug?
No. The Basic Package is strictly for minor, quickly identifiable issues (e.g., small CSS/HTML error or tiny JS logic flaw). If the fix requires more than one hour of work, I will suggest upgrading to the Standard or Premium package.
