2.50

The accessibility is apparently really bad! Probably both for disabled people and everyone of us when we need some accessibility!
Number of error type: 8 3.40
Number of errors: 34 1.60

Problems:

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 2.6:1. Recommendation: change text colour to #677986.
Duplicate id attribute value "title" found on the web page.
Duplicate id attribute value "wordpress-logo-simplified-cmyk" found on the web page.
Heading tag found with no content. Text that is not intended as a heading should not be marked up with heading tags.
Fieldset does not contain a legend element. All fieldsets should contain a legend element that describes a description of the field group.
A fieldset element does not have a name available to an accessibility API. Valid names are: legend element, aria-label undefined, aria-labelledby undefined.
Anchor element found with no link content and no name and/or ID attribute.
Iframe element requires a non-empty title attribute that identifies the frame.
