I approved a reader comment, but it is not showing as a comment on the blog. When I tried to republish the blog, I got the following error message:

An error occurred publishing category '9784': Publish error in template 'Category Archive': Error in <mtSetVarBlock> tag: Error in <mtIf> tag: Invalid tag "CategoryDescription specified.

How do I make the comment show and what does that error message mean?

Hi Erica,

Errors like this can be thrown in Movable Type 4.

As the message shows, you have a template called “Category Archive” that contains a SetVarBlock block tag that contains an If tag with a tag parameter. Likely there is an extra quote there, perhaps from an attempt to copy and paste “CategoryDescription”.

For instance, I can generate the same error with the code:

<mt:SetVarBlock name="VAR_NAME">
  <mt:If tag='"CategoryDescription'>

Note the extra double quote before the tag name.

For the curious, this error comes from, though this code was refactored in MT 5.
