Antisamy is aggressively filtering some HTML content, causing some plugins to malfunction

Affected plugins are those that use wiki markup to enter embeddable javascript inside macros. This is known to affect:

1. Run macro
2. Some bespoke macros created by customers

Because of the potential for this to disrupt functionality of various important plugins, we have removed Confluence 5.5.4 from the download page.

If you are currently running Confluence 5.5.4 and your plugins are all working as expected, you are not affected by this bug and can continue to use Confluence 5.5.4.

If you are on Confluence 5.5.4 and are experiencing issues with your plugins, please contact Support.
