I think I'm using Vanilla MT 2.5 Individual Entry Archive, but after editing a
lot of comments (deleting spam, some comment author names have unusual
character sets):

CODE
An error occurred:

Building entry 'MINI is smart' failed: Build error in template 'Individual Entry Archive':
Error in <MTEntryIfAllowComments> tag: Error in <MTCommentDate> tag:
You used an MTCommentDate tag without a date context set up.  

MT::App::CMS=HASH(0x266764) Use of uninitialized value at lib/MT/Template/Context.pm line 928.


Any idea what specifically is now working, or why i would suddently break ?
