Please note that we originally developed Total Validator because of mistakes and limitations with other tools. So if you have used another tool that reports different results, it could be a problem with that tool.
Many other validators and help sites do not use the official standards but are interpretations of them. As a result they tend to be rife with popular assumptions which are actually mistakes. Free tools and sites in particular tend not to be regularly updated, and so often fall behind constantly evolving standards.
However, if you do think you've found a genuine error, then please report it using our Contact Form. We are always happy to investigate, and if necessary, fix any issues with our products, to provide the best user experience.
