診断

環境

  1. The HTML macro is enabled

原因

The XHTML renderer is experiencing problems with HTML somewhere in the space and is unable to export it.

回避策

  1. Disable the HTML macros to successfully export the content
  2. Or remove the HTML content until you're able to find the offending content, however there could be multiple pieces of content causing issues
