Laravel E-Commerce Debug & Update

My PHP/Laravel e-commerce site has started throwing page-loading errors and several product or category URLs now land on 404s. I’ve already confirmed that the server is fine, so the issues appear to be inside the codebase or route definitions.

Here’s what I need done:

• Identify and eliminate the root cause of the slow or stalled page loads (both server-side and any JavaScript that may be blocking rendering).
• Trace every broken link the crawler log reports, correct routes or controller methods, and make sure the fix persists after cache clears.
• Update any outdated Laravel or Composer packages only where necessary for stability; leave custom modules untouched unless they cause the errors.
• Document each change clearly in a short change-log and commit messages so I can track what was modified.
• Push the working version to the staging branch for review; once I sign off, merge to production.

Acceptance criteria: the homepage, product listings, cart, and checkout must all load in under two seconds, and no 404s should appear on a full crawl. A brief hand-off note explaining what was fixed and why will complete the job.
