Problem 

The create button only returns a warn message with the following text: "Can't create the issue. The configured Jira responded the following..." 

Solution

One or more required fields are not included in the Issue Form - create form or hidden (and there is no default value specified).

You can:

• Include the field.
• Specify a default value or unhide the field.
  

Problem

The create button only returns a warn message with the following text: "Anonymous access must use CAPTCHA."

Solution

Since version 2.3, users of Confluence, who are not logged in to Jira, can create Jira Issues. But these users have to fill in a captcha.

You can:

• Disable anonymous access to the page.
• Add the Issue Forms - captcha - Macro to the form.
