We have have Confluence version 5.9.4
We were using HTML macros still last week. And today when we try to use HTML macros it says
"The macro 'html' is unknown. It may have been removed from the system."
I checked on Add-on - system - Confluence HTML
html - Use HTML code within a Confluence page (Legacy)
html - (html-xhtml) - Use HTML code within a Confluence page
html-include - (html-include) - Retrieve an external HTML file and include it in the page (Legacy)
html-include - (html-include-xhtml) - Retrieve an external HTML file and include it in the page
This modules are enabled.
What can be done to work HTML Macros again
