In the file TWiki/CommentsTemplate there is a line

 %TMPL:INCLUDE{"%TWIKIWEB%.UserCommentsTemplate"}%

And I have such a UserCommentsTemplate file

If I change the include to

%TMPL:INCLUDE{"TWiki.UserCommentsTemplate"}%

Then it gets included OK. It seems the TWIKIWEB is not expanded inside the TMPL:INCLUDE

I was just diagnosing this same problem this morning, after upgrading to 4.0.1. However, I don't think you want the TWiki. on there, since that defeats the search path for the template. So, I think the include line should be changed to:

%TMPL:INCLUDE{"UserComments"}%

Note that without the explicit web name, you have to leave off Template since the template include processing adds that portion itself (otherwise, you get a search for UserCommentsTemplateTemplate).

The include line for %TWIKIWEB%.UserTemplates should also be changed to reference TWiki.UserTemplates. Here, I think you do want the explicit web, as that was the only way it worked when UserTemplates was in (current) use.

The fixer of Item1412 changed the templates, and then didn't revert the change correctly which is the reason for the confusion. Reverted in SVN 8788 and uploaded
