Original Problem
This legacy thread preserves a broad but still useful validation problem: the site owner was trying to untangle doctypes, validators, broken layout, and hundreds of reported errors at the same time.
The value is not one perfect fix. It is the preserved support path that shows how validation work felt in practice when markup mistakes, scripts, and page structure were all colliding.
Selected Useful Comments
- One support reply says online validators can be overwhelming and that getting pages to validate is a long process even for experienced site owners.
- The user reports more than
200errors on a live site and says doctypes or scripts were scrambling the page. - A later reply identifies duplicate
htmlandbodytags and eventually narrows one failure down to problematic JavaScript.
Editor Context
This is a worthwhile historical troubleshooting page, but it is still broad enough that it should stay framed as a preserved thread rather than a current validation tutorial.
The strongest durable takeaway still belongs inside Website Optimization Techniques Archive: validation work is layered, and one visible error rarely explains the whole page.
