Problems:

A searchinput element does not have a name available to an accessibility API. Valid names are: label element, title undefined, aria-label undefined, aria-labelledby undefined.
A link points to a named anchor "totop" within the document, but no anchor exists with that name.
Anchor element found with a valid href attribute, but no link content has been supplied.
A textinput element does not have a name available to an accessibility API. Valid names are: label element, title undefined, aria-label undefined, aria-labelledby undefined.
Iframe element requires a non-empty title attribute that identifies the frame.
A element has insufficient contrast at this conformance level. Expected a contrast ratio of at least 4.5:1, but text in this element has a contrast ratio of 3.34:1. Recommendation: change text colour to #fff.
A element has insufficient contrast at this conformance level. Expected a contrast ratio of at least 4.5:1, but text in this element has a contrast ratio of 2.32:1. Recommendation: change background to #af6400.
A element has insufficient contrast at this conformance level. Expected a contrast ratio of at least 4.5:1, but text in this element has a contrast ratio of 2.32:1. Recommendation: change text colour to #af6400.
A form does not contain a submit button, which creates issues for those who cannot submit the form using the keyboard. Submit buttons are INPUT elements with type attribute "submit" or "image", or BUTTON elements with type "submit" or omitted/invalid.
Img element is the only content of the link, but is missing alt text. The alt text should describe the purpose of the link.
Info: Too many unique problems to show them all.
