My responsive WordPress site needs a concise round of maintenance and polish. The top priority is the mobile menu: its layout is broken, so the navigation looks messy on phones and small tablets. I’d like you to trace the root cause—whether that’s a CSS tweak, a template override, or a plugin conflict—and restore a clean, reliable slide-out menu. While you’re inside the codebase, please: • Update the PHP-based theme files and database structure because the current WordPress version requires it. • Audit active plugins; disable or patch anything that’s interfering with responsiveness. • Run a full front-end sweep so every page (home, product, contact, etc.) renders correctly on desktop and mobile. • Suggest or apply subtle design improvements where you see obvious quick wins; solid design instincts are a plus. Provide your OVH Nichandle so you will have complete access to the OVH hosting panel, database, and file system. When you’re done, I expect the site to be 100% secure, error-free, visually consistent across devices, and documented with a short summary of the changes you made and any recommendations for future upkeep.
