症状

When you have the Inline Edit mode enabled in JIRA (5.1 - 5.1.3) with SSL, it brings some Security Warning popups in IE8.
If you disable it, the errors disappears.

原因

See JRA-26838. 

回避策

• Disable "Mixed Content" Warnings in IE
  Go to Tools -> Internet Options and select the Security tab. Make sure the "Internet" zone is selected and then click the "Custom Level" button. Scroll-down the list of options and set the "Display mixed content" setting from "Prompt" to "Enable."

• Disable the Inline Edit mode to avoid the warning messages. By default Inline editing is enabled. It can be disabled by simply switching the Inline edit option to OFF via the General Configuration page. This has to be done by JIRA administrators. 
• Upgrade to IE9. 

ソリューション

Upgrade to JIRA 5.1.4 or newer.
