Problems:

A form field should be labelled in some way. Use the label element (either with a "for" attribute or wrapped around the form field), or "title", "aria-label" or "aria-labelledby" attributes as appropriate.
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.
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 3.32:1. Recommendation: change text colour to #70777d.
Img element is the only content of the link, but is missing alt text. The alt text should describe the purpose of the link.
Anchor element found with a valid href attribute, but no link content has been supplied.
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 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.
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.
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.
Info: Too many unique problems to show them all.
