I need assistance with updating my WordPress website. Specifically, I’d like to refine the design and layout of the header and footer, as well as adjust the navigation links by adding or removing them as needed. Additionally, I'd like to add a new portfolio page to showcase my work. Another critical issue that needs addressing is a persistent error message preventing one of my pages from loading properly. It's vital that the issue is diagnosed and resolved to ensure seamless functionality. If you have expertise in WordPress, web design, and troubleshooting, I’d love to work with you on this project.
