Resolve solve Error on IrishBestDeal.com

My entire site, irishbestdeal.com, has suddenly started throwing All Type Found errors. The homepage, every product page, and even the contact page are unreachable, yet I haven’t touched the structure, settings, or plugins recently.

I need someone who can dive straight into the server, CMS, or routing files (htaccess, nginx config, database mappings—whatever applies) and pinpoint what broke. Once the root cause is clear, I want the live URLs working again with no collateral issues for SEO, analytics, or checkout flow.

Deliverables
• Diagnosis summary outlining what caused different type Eroor.
• Full fix applied to restore access to the homepage, product pages, and contact page
• Confirmation that all internal links resolve correctly and no new errors appear in Google Search Console or server logs

I’ll provide hosting and admin credentials as soon as we start, and I’d like a quick turnaround with a brief hand-over on how to avoid the problem in the future.
