Hello,
We recently upgraded our Confluence Data Center version to v8.5.17 from v8.5.14. We use the Content Formatting for Confluence plugin. The HTML comments that were added using the HTMLComment macro in the wiki pages do not show any content now. The macro code placeholder is still in the .txt file, but the content is not included.
When we add new comments the text is displayed correctly.
New:

Old (before upgrade):

I am guessing this is a DB issue. Any help is appreciated.
