WordPress Repair, Speed, Upgrade

My WordPress site needs a full tune-up. Pages are loading far too slowly, several internal links lead straight to 404 errors, and the current layout feels dated and uneven across devices. I want to upgrade the installation to the latest stable WordPress release, make sure every plugin and theme survives the jump, and come out the other side with a site that looks crisp and performs quickly.

I will hand over WP admin and hosting panel access along with a recent backup. Please stage your work in a test environment first and move everything to production only after I sign off.

Deliverables
• WordPress core upgraded safely, with a fresh backup created before you begin
• All broken links/pages repaired and verified
• Page-load speed optimised and an after-action performance report provided (PageSpeed/Core Web Vitals or similar)
• Layout cleaned up and fully responsive so it feels modern on desktop, tablet, and mobile
• Brief changelog + documentation and one week of post-launch bug support

OUR BUDGET IS $100 FOR THE WORK.
