User macro issue if macro contains body and icon URL

[thgmx]

Hello community,

when I define a user macro which contains no body and an icon URL I don't succeed to insert this macro in a page. What happens is:

• The page waits for about two minutes to save changes.
• The buttons "Preview", "Update" and "Close" remain unclickable until I open and close the dialog "Unpublished Changes" (by clicking "Changes saved").
• After having closed the dialog the mentioned buttons ("Preview", ...) are clickable again.
• Click on "Update": page will be saved but the place where I tried to insert the macro remains empty.

The macro works fine if it does contain a body or if I don't define an icon URL.

My Confluence version is 6.2.3 (server). Can anybody help?

Best Regards
