I have a question regarding the web content accessibility guidelines.
I have been asked to review whether a web application respects the WCAG 2.0 AA web standard.
I have to indicate the criteria that are in error, with suggestions on how to correct them.
In the application, there is a page that requires cookies to work properly. If the user has disabled cookies, there is a generic error message that appears.
Internal error occurred while processing your request.
Please try again later.
In my opinion, this would fail on the criterion
The intent of this Success Criterion is to help users avoid making mistakes when their input is required. To help avoid mistakes it is good user interface design to provide simple instructions and cues for entering information. Some users with disabilities may be more likely to make mistakes than users without disabilities or recovery from mistakes may be more difficult, making mistake avoidance an important strategy for users with disabilities. People with disabilities rely on well documented forms and procedures to interact with a page. Blind users need to know exactly what information should be entered into form fields and what the available choices are. Simple instructions visually connected to form controls can assist users with cognitive disabilities or those accessing a page using a screen magnifier.
The intent of this Success Criterion is not to clutter the page with unnecessary information but to provide important cues and instructions that will benefit people with disabilities. Too much information or instruction can be just as much of a hindrance as too little. The goal is to make certain that enough information is provided for the user to accomplish the task without undue confusion or navigation.
However, some elements of the criterion seem to be focusing on user input.
I think this would also fail the 3.3.3 Error Suggestion criterion since there is an error and possible solutions are known.
However, 3.3.3 also seems to be focusing on user input.
This could also be a user experience issue that falls beyond the scope of what I was asked, but should I mark those criteria as failed ?
